Xylan Blue PTFE ASTM A193 B7 B7M A320 L7 L7M Stud Bolt with ASTM A194 2H 2HM Gr7 Gr7M Heavy Hex Nuts

Description:

ASTM A193 B7 B7M A320 L7 L7M Stud Bolt threaded rod are commonly used in offshore flatform, oil and gas. With PTFE coating, it is in high anti-corrosion.

The specification for ASTM A193 covers alloy and stainless steel bolting for pressure vessels, valves, flanges, and fittings for high temperature or high pressure service, low temperature, or other special purpose applications. The ASTM A193 specification covers bars, bolts, screws, studs, stud bolts, and wire. The material may be further processed by centerless grinding or by cold drawing. Below are some of the ASTM A193 grades used commonly.

Common ASTM A193 specifications:

ASTM A193 B7 Alloy steel, AISI 4140 or 4142, quenched and tempered

ASTM A193 B6 Stainless steel, AISI 410, heat treated

ASTM A193 B8 Class 1 Stainless steel, AISI 304, carbide solution treated.

ASTM A193 B8M Class 1 Stainless steel, AISI 316, carbide solution treated.

ASTM A193 B8 Class 2 Stainless steel, AISI 304, carbide solution treated, strain hardened

ASTM A193 B8M Class 2 Stainless steel, AISI 316, carbide solution treated, strain hardened

ASTM A193 B8T Class 1 or 2 Stainless steel, AISI 321, with additional element of Titanium

ASTM A193 B16 Chromium-Molybdenum-Vanadium, similar to B7 with Vandium added

ASTM A193 B7M Similar properties as B7 but with specialized heat treating to create differing mechanical properties

ASTM A193 B8R Stainless steel, AISI 209, also known as Nitronic 50, nitrogen strengthened

ASTM A193 B8S Stainless Steel, AISI 218, also known as Nitronic 60, nirtrogen strengthened
