800H can resist corrosion of many corrosive media. Its high nickel content makes it resistant to stress corrosion cracking in aqueous corrosion conditions. The high chromium content provides better resistance to pitting and crevice corrosion cracking. The alloy has good corrosion resistance to nitric acid and organic acids, but limited corrosion resistance in sulfuric acid and hydrochloric acid. Good corrosion resistance in oxidizing and non-oxidizing salts, in addition to the potential for pitting corrosion in halides. It also has good corrosion resistance in water, steam and mixtures of steam, air and carbon dioxide.

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 A193 Grade B7 specification covers the requirements for high strength alloy steel bolting materials for high temperature or high pressure service and other special purpose applications. It is a standard specification that defines typical chemical composition, mechanical properties, hardness requirements, preferential heat treatment, product marking, certification, and other requirements for bolted connections used in pressure vessel service, valves, flanges, and fittings. ASTM A193 defines SI (metric) and inch-pound units.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

ASTM A193 Grade B8M Grade 1 Fasteners are similar to Grade B8 but are made of AISI 316 stainless steel instead of AISI 304 stainless steel. Type 316 stainless steel has better corrosion resistance than type 304 stainless steel due to the addition of molybdenum.

ASTM A320 Grade L7M bolts and studs are also made from quenched and tempered alloy steel.

Alloy steel is divided into two categories: high-alloy steel and low-alloy steel. Low alloy steel flanges, on the other hand, contain about 0.05 ¨C 0.25% carbon and up to 2.0% manganese.

The plates are annealed in different condition which offers them strength. Since these plates are to be worked at high temperatures and pressure environment therefore the elements included in it matters a lot. What elements are added in the manufacturing add different properties for example, high level of chromium adds excellent corrosion resistance. It also offers excellent oxidation resistance. Resistant to oxygen is important in petrochemical and gas industries and therefore these plates are used.

Gold Steel P91 of A335 EFW Pipe is an austenitic compound whose elasticity and creep strength can be improved by cold working. These pipes are widely used in oil and gas, power plants, shipbuilding, heavy engineering and other industries. All products meet or exceed industry standards of API, ASTM, ASME, ANSI and other national and international standards.

It is the addition of other elements that make alloy steel stronger. Heat-treated elements such as silicon and manganese give alloy steels improved properties and additional benefits, such as increased corrosion resistance or improved weldability.

Different types of ASTM A182 F5 forged fittings include threaded flanges, slip flanges, weld neck flanges, socket weld flanges, blind flanges and lap flanges.

WPHY 52 Pipe fittings are manufactured as per MSS SP 75 shall be furnished in the heat treated condition.We offer a wide assortment of ASTM A860 WPHY 52 Fittings that cater to the prerequisite of different industries such as engineering, chemical, refineries, machine apparatuses, and numerous others.

These are used in applications where the resistance required is not much and general corrosion resistance is required.

The ASTM A194 specification covers a wide variety of carbon, alloy, and martensitic stainless steel nuts in sizes ranging from 1/4 to 4 inches and metric M6 to M100 nominal. It also covers austenitic stainless steel nuts in the size range of 1/4 inch and M6 nominal and above. These nuts are used for high pressure or high temperature service, or both.

In order to improve the thermal efficiency of the reheat steam pipeline of the power plant, the reheat temperature can be designed to be 621¡ãC, that is, the supercritical temperature. The United States first developed ASTM A335 P92 alloy steel in the late 1980s to meet the heat resistance requirements of this high temperature power plant. Alloy Steel P92 is an improved version of ASTM A335 P91 alloy with deliberate additions of tungsten, vanadium, niobium, reduced molybdenum content to fine-tune the ferrite/austenite ratio, and carefully controlled boron and nitrogen content.

SA182 F1 forged flanges are used as connecting parts to create piping networks for cylinders, valves, pumps and other equipment. Combine two different parts of the machine. To make the structure stronger, it should be an attachment to the frame.

While chromium is an important alloying agent in a335 P91 piping, it is known to prevent corrosion and has a high resistance to oxidation at high temperatures. Since these pipes are surface treated or coated, they are also protected against corrosion. Surface coating can be accomplished by various techniques such as passivation, phosphating, oil immersion, varnishing and shot peening.
