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.

These Alloy F5 Flange are used for transferring liquid and other fluids to several industries. We are manufactured by a team of nimble-fingered professionals using high quality raw material, modern tools and advance technology.

Alloy steel seamless pipes are widely used in medium and low pressure fluid pipelines, casings, boiler tubes, oil and gas industry, chemical industry, power generation industry, transformers, agriculture, bearings, general engineering, automobiles, hydraulics, railways, mining, construction, aviation Aerospace, medical, defense and electric motors. P91 alloy steel is mainly used in the power industry. For welded structures, the ASME Boiler and Pressure Vessel Code limits the carbon content to less than 0.35%. Alloy steels are ideal for applications that require higher strength, tougher or better wear resistance than standard carbon steel grades.

ASTM A193 Grade B7M bolts and studs have the same chemical composition as Grade B7 (quenched and tempered medium carbon alloy steel) but have lower strength requirements requiring 100% hardness testing on all fasteners manufactured in the batch. Grade B7M bolts are resistant to chloride, sulfide and hydrogen stress corrosion cracking (SCC) and are often used in sour gas service.

Alloy steel sounds like: steel that contains a specific amount of alloying elements. Generally, alloying elements make steel stronger and more resistant to shock or stress. While the most common alloying elements include nickel, chromium, molybdenum, manganese, silicon and copper, many other alloying elements are also used in the production of steel.

Whether manufactured to ANSI, ASME or custom standards, flanges are critical to manufacturing, utility and industrial applications around the world.

Alloy steel UNS K12822 round bars are widely used in numerous industries for the manufacture of different kinds of components. We provide a full range of alloy steel 15Mo3 round bars which are widely used in engineering, construction and other industries.

ASTM A 182 Alloy Steel GR F11 Round bars are generally considered less robust than stainless steel alloys, and their price plays an important role in the purchase.

SA335 material is available in different pressure grades, SA335 P11 material is special in that it can be used in most high pressure and high temperature services. In this range there are seamless pipes and welded pipes, which are used for different requirements.

Blind flanges can also be used to seal a nozzle opening on a pressure vessel.

ASTM A182 Stainless Steel Flanges are manufactured per ASME B16.5 150#, 300#, 600#, 900#, 1500#, 2500#.

The Alloy Steel Blind Flanges are used to close a pipe connection. There are different types and grades of the blind flanges as well.

Its greatest advantage is that it can be assembled without welding, which explains its use in low-pressure service at ordinary atmospheric temperatures and in highly explosive areas where welding creates a hazard.

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.

Weld Neck Flange is expensive because of its long neck and cost of people for contact WN flange with pipeline or fitting but is preferred for high-stress applications. The necks, or hubs, transmits stresses to the pipeline.

The heat treatment could be heat treated according to any of the WPHY 52 specification by either tempering, normalizing, quenching or stress relieving.A860 refers to the high quality of the fittings.

ASTM specifications recommend a minimum Charpy impact value for ASTM A320 L7 Stud Bolts to be 20-ft-lbf @ -150F. The Charpy impact test determines the total amount of energy that is absorbed by a material during fracture, thereby indicating the material¡¯s notch toughness.
