Materials

B8M Grade 1 fasteners require carbide solution treatment, while Grade 2 fasteners require additional strain hardening operations to increase strength and reduce susceptibility to wear.

ASTM A194 specification covers carbon, alloy and stainless steel nuts for high pressure and/or high temperature service. American National Standard Heavy Duty Hex Series (ANSI B 18.2.2) shall be used unless otherwise specified. Nuts no more than 1 inch in nominal size shall conform to UNC Series Class 2B.

Nuts with a nominal size over 1 inch shall be a UNC Series Class 2B fit or an 8 UN Series Class 2B fit. High strength ASTM A194 grade 2H nuts are common in the market and are often replaced by ASTM A563 grade DH nuts due to the limited availability of DH nuts in certain diameters and finishes.

ASTM A194 Class 2h bolts are carbon base steel heavy duty hex nuts. Sa194-2h material is a common high strength nut. This specification ASTM A194 Class 2h washers are typically used in conjunction with the following fastener standards – A193 Class B7, A325, A490.

ASTM A194 2H Heavy Duty Hex Bolts are the core product and are in stock. HT PIPE is a leading supplier of ASTM A194 2H Heavy Duty Hex Nuts. These are heavy duty hex nut type bolts as directed by ASTM A-193 specification.

The ASTM A307 specification covers carbon steel bolts and studs ranging in diameter from 1/4″ to 4″. This is your everyday mill bolt specification, usually made from A36 round bar. There are three grades A, B and C* for tensile strength, configuration and application, respectively. See the mechanical properties chart for subtle strength differences within each grade.

HT PIPE manufactures and distributes a wide range of carbon steel fasteners including u-bolts, studs, carriage bolts and more. Carbon steel is a common material for fasteners due to its good tensile strength and ability to withstand loads. It responds well to heat treatment with minimal work hardening and brittleness.

U-Bolts are easy to machine and can meet the tight tolerances required for thread and fastener configurations. Carbon steel is also an economical metal. Carbon steels are classified by the amount of carbon in the alloy, which affects the properties of the steel. Mild steel with a carbon content of 0.05-0.3% is ductile and ductile. Low tensile strength and hardenable by carbonization. It is the lowest cost of carbon steel alloys.

U-Bolt medium carbon steel contains 0.3-0.59% carbon, which provides the alloy with increased strength and good wear resistance. It is easy to machine and is used for forging and auto parts. High carbon steel and ultra-high carbon steel are very strong and are used in springs and high strength products. These alloys can be tempered to very high hardness without becoming brittle and are used in very high wear applications. The carbon content of these alloys is 0.6-0.99% high carbon steel and 1.0-2.0% ultra-high carbon steel.

Because carbon steel flat wahsers still have a lot of carbon in them that oxygen would prefer to bond with. Chromium in carbon steel lock washers also induces ferromagnetism in the steel, which is not desired in some applications, and nickel also helps with this.

Our carbon steel ferrule manufacturing unit is capable of producing large and custom orders from our customers around the world. These high chromium carbon steels, while belonging to the stainless steel category, are not fully corrosion resistant. The elements in carbon steel groove washers have a large effect on heat treatment; because they tend to slow the diffusion of atoms through the iron lattice, thereby delaying the allotropic transformation. The hardenability of carbon steel washers can be improved by adding elements such as manganese, molybdenum, chromium, nickel and boron.

These washers are manufactured by our skilled professionals using top quality raw materials in accordance with established industry norms. We offer ASTM A307 carbon steel washers in a variety of specifications and can be custom designed to customer specified specifications. Backed by a dedicated team of professionals, we are committed to supplying a premium line of ASTM A307 Carbon Steel washers.

The specification for Iso Class 4.8 standard covers Grade 4.8 fasteners like Bolts/Screws/Studs. This type of fastener Class 4.8 Bolt could either have Coarse thread and fine pitch thread formation. The standard Class 4.8 Carbon Steel Bolt has been manufactured from Low or medium carbon Alloy Steel.

Carbon steel washers are made of very high quality raw materials, which ensure high durability at their user end. These carbon steel washers widely find their valuable application in various industrial fields.

The typical hardness of mild steel is Rb70/85. Parts requiring high strength and wear resistance or for use in critical components can be fabricated from high carbon steel or case hardened after fabrication. Chromate coatings can provide corrosion protection. Carbon steel washers are used for fastening in various industries.

Carbon steel is defined as any steel with a carbon content not exceeding 2.1% by weight. Carbon steel bolts become harder and increase in strength after heat treatment as the carbon content increases. However, the ductility of the steel decreases.

Within this specific category of mild steel is another steel called High Strength Low Alloy Steel, or HSLA for short. Although HSLA screws belong to the mild steel category, it can be noted that HSLA screws also contain other elements in their alloys, such as copper, nickel, vanadium and molybdenum.

Regardless of the heat treatment applied to the carbon steel alloy, the higher carbon content in the material reduces the weldability of carbon steel fasteners, while also effectively reducing the melting point of the bolt. Most carbon steel studs are generally softer.

The combination of all elements of the bolt accounts for 10% of the weight of the steel. As the name suggests, HSLA bolts are heat treated for higher strength. These washers remain ductile, making them easy to form and machine, while exhibiting higher corrosion resistance than ordinary mild steel.

They also exhibit low strength. However, mild steel is highly flexible. High ductility is a property that makes the material ideal for machining and welding.

Medium carbon steel bolts, anchor bolts, screws, studs, nuts and self-drilling screws contain between 0.25 – 0.60% carbon and 0.60 – 1.65% manganese by weight. The mechanical properties of these studs are improved by heat treatment.

No different elements – used as an alloying agent, not other types of steel, which makes nuts and bolts known as low-cost bolts. Carbon steel nut and bolt grades are divided into three different categories based on the carbon content of mild, medium and high carbon steels.

High carbon steel bolts have a carbon content between 0.60 – 1.25%. High carbon steel alloys have manganese content in the range of 0.30 – 0.90%. Of all three grades, high carbon steel threaded rod has the highest hardness and toughness while exhibiting the lowest ductility. The high wear resistance comes from the fact that these screws are almost always hardened and tempered.

Nuts are attached to corresponding bolts or rods to secure items. Cap nuts protect the threads of fasteners by preventing them from protruding. The locknut and locknut are locked on the bolt to prevent loosening. Thumb nut and wing nut are manually adjustable. The connecting nut is an extension for connecting two threaded rods.

Carbon steel bolts are one of carbon steel fasteners. There are different types of carbon steel and they all have high hardness. HT PIPE is a leading manufacturer and supplier of carbon steel nuts and bolts and other fasteners.

There are studs, washers, threaded rods, screws, etc. Each type of fastener has its own advantages and application requirements. Carbon steel screws can be used without nuts. It can be driven with a screwdriver.

Carbon steel studs are used to hold two components together in tight spaces. Carbon steel materials have poor ductility but high hardness. This allows carbon steel to be used in applications that require high hardness, such as carbon steel studs in the oil and gas industry and in power transmission lines.
