It is a standard specification defining typical chemical composition, mechanical properties, hardness requirement, preferential heat treatment, product marking, certification and other requirements, suitable for bolting used in pressure vessel service, valves, flanges and fittings. ASTM A193 defines both SI (Metric) and inch-pound units.

Bolts are chrome molybdenum heat treated steel according to ASTM A193 B7m specification for bolts. The primary alloy components of ASTM A193 Grade B7 bolts are chromium and molybdenum. These ASTM A193 B7 Metric Bolts are manufactured by heat quenching and tempering. Heat treating A193 B7 bolt material helps to develop desired mechanical properties such as increased tensile strength of ASTM A193 B7 hex bolts after heat treatment.

Alloy steel pipe is an economical section steel. Widely used in the manufacture of structural and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames and steel scaffolding for construction. Making ring parts with alloy steel pipes can improve material utilization, simplify the manufacturing process, save materials and processing time, such as: filling bearing rings, jack sleeves, etc. At present, steel pipes have been widely used in manufacturing.

The addition of chromium and molybdenum to a182 grade f9 enhances the corrosion resistance of the flange.

For A335 steel pipe, the addition of molybdenum (“Moly”) increases the strength and elastic limit of the steel, and enhances the wear resistance, impact quality and hardenability of the steel. It also improves softening resistance, makes chrome steel less brittle and prevents pitting corrosion. Chromium is also a key element in stainless steel alloys, preventing oxidation of the steel at high temperatures and improving the corrosion resistance of the steel. It improves the tensile, yield and hardness properties of low alloy pipes at room temperature.

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.

A blind flange is a solid flange as shown below. The purpose of these is to block off a section of pipe or a nozzle on a vessel that is not used.

Alloy Steel Flanges, Alloy Flanges are carefully designed using current technology under the visionary guidance of accomplished professionals in the manufacturing sector.

ASTM A182 Alloy Steel Forged Fittings are manufactured according to the ASTM A182 specification, which covers high pressure and high temperature service flanges covered by ASME B16.11, MSS-SP-79/ 83/ 95/ 97 and BS3799 standards.

Seamless pipes are used with slip on flanges to make the process smooth. The Alloy Steel Blind Flanges are used to close a pipe connection.

The corrosion resistance of SA 335 P91 seamless pipe is much higher than that of carbon steel. Grade P91 is a reference for the chemical composition of alloy steels. A chromium-molybdenum steel, the chemical composition of ASTM A335 P91 alloy steel pipe consists of 9% chromium and 1% molybdenum and vanadium.

We feel proud to introduce ourselves as the well-known manufacturers, exporters and suppliers of Alloy Steel F21 Flanges.

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.

ASME SA335 grade p11 tubing contains trace amounts of carbon, sulfur, phosphorus, silicon and manganese. For example, the addition of chromium is known to improve the tensile strength, yield strength, fatigue resistance, wear resistance, and hardness properties of the alloy. The addition of these properties is ideal for preventing oxidation in high temperature applications.

Alloy 20 (Alloy 20) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, pitting corrosion and crack corrosion. Therefore, alloy 20 has the name of anti-corrosion alloy; it has a wide range of applications: such as: chemical, food, medicine, power production and plastics industries will use it. For resistance to pitting corrosion and chloride corrosion, stress corrosion cracking problems, etc., alloy 20 is often used.

Carbide solution treatment, also known as solution annealing, is a process in which fasteners or stainless steel rods are heated and then water quenched to ensure maximum corrosion resistance. A193 Grade B8 Grade 2 bolts are strain hardened after carbide solution treatment to improve strength properties and reduce the potential for wear.

A wide range of industries, shops and systems rely on high-performance flanges, and custom pipe flanges are often critical to getting the job done right.
