ASTM A453 GR 660 CLASS B Threaded Bars

What are ASTM A453 GRADE 660 CLASS B THREADED BARS?

ASTM A453 GRADE 660 CLASS B THREADED BARS are precipitation hardening austenitic stainless steels that have a relatively high content of nickel in their chemistry. This allows these Grade 660 Class B Threaded Bars to be used at higher temperatures than those of other stainless steels, and it also acts as an austenite stabilizer.

These A453 Grade 660 Class B THREADED BARS have several other advantages as well, including higher creep, stress-to-rupture, and tensile strength at elevated temperatures. In addition, ASTM A453 Stainless Steel GR 660 Class B Threaded Bars are more resistant to pitting and crevice corrosion than other chromium-nickel austenitic grades. Several types of Stainless Steel Fasteners are available like Stainless Steel 304 Fasteners, Stainless Steel 310S Fasteners, etc.

The materials produced in accordance with ASTM A453 specifications are subjected to various tests and requirements. These include elongation, reduction of area, yield strength, tensile strength, and Brinell and Rockwell hardness. Additionally, hardening and solution treatment requirements are specified for each material class. We also manufacture other products such as Duplex Steel UNS S31803 Nuts, Inconel 601 Fasteners, etc.

ASTM A453 GRADE 660 CLASS B THREADED BARS are manufactured using high-quality stainless steel materials and modern techniques to ensure superior strength & durability. ASTM A453 GR 660 CLASS B Tie Bars are ideal for use in a range of environments and corrosive media.

Grade 304 Stainless is a common grade of stainless with excellent corrosion resistance and ductility in both annealed and hardened conditions. It is used in various applications, including gas and steam turbine components, pump shafts, piping, heat exchangers, and gas and oil processing equipment.

Custom ASTM A453 GR 660 CLASS B Double Ended Studs is a martensitic age-hardening stainless with moderate strength and excellent corrosion resistance. It is a versatile material with good machining capabilities. It is a popular choice for valve components, pumps, bushings, engine valves, retorts, and baskets.

ASTM A 453 GR 660 CLASS B STUDBOLTS

ASTM A453 GRADE 660 CLASS B THREADED BARS are made from a combination of materials, including carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, and titanium. These materials offer superior strength and corrosion resistance at elevated temperatures. These fasteners are used for pressure vessels, darting boilers, pipeline flanges, and valves that require high-temperature service. They also have excellent tensile strength and elongation.

This stainless steel is a molybdenum-bearing austenitic stainless steel that offers better corrosion resistance than a conventional chromium-nickel alloy. In addition, it can resist pitting and crevice corrosion in chloride environments. ASTM A453 Grade 660 fasteners are classified into four property classes, with each type designated with different tensile and stress rupture properties. They are designed to resist high temperatures up to 700 degrees Celsius. They are manufactured to international standards such as DIN 931, ISO 4014, ASME B18.2.1 UNI 5737, and more, in metric and inch sizes with UNC, UNF, UNEF, ISO, BSW & BSF threads.

They are manufactured using high-quality alloys and modern techniques. They are available in a variety of sizes, shapes, and dimensions.

These fasteners are made from a precipitation hardening austenitic stainless steel that has excellent tensile strength and corrosion resistance properties. They are suitable for a wide range of applications and can handle temperatures up to 704 degrees C.

A453 Gr 660 bolting materials include rolled, forged, and hot-extruded bars, as well as stud bolts, screws, nuts, and hex bolts. These are intended for use in high-temperature services, such as for pressure vessels and valve flanges. This specification requires that these fasteners be subjected to tension, stress-rupture, and hardness tests. These tests determine the material's yield strength, tensile strength, elongation, reduction of area, Brinell hardness, and Rockwell hardness.

What are Grade 660 Class B Threaded Bars?

ASTM A193 Grade B8C hex bolts are primarily used in applications that require high strength and corrosion resistance. They are suitable for use in industries such as chemical processing, petrochemical, and oil & gas, where equipment & structures are subjected to harsh environments.

What is the yield strength of grade 660 Class B Threaded Bars?

The grade 660 Class B threaded bars yield strength can vary depending on the specific material composition and heat treatment process. However, these threaded bars typically have a minimum yield strength of 105 ksi (kilopounds per square inch) or approximately 724 MPa (megapascals).
