Carbon Steel Gr4.8 Gr8.8 Alloy Steel B7 B7M DIN975 DIN976 Black
Coating Stud Bolt Fully Threaded Rod
DIN975 DIN976 Black Coating Stud Bolt Full Threaded are commonly
used in offshore flatform, oil and gas and construction, building
Stud bolt, Threaded rod (threaded bar), DIN975, DIN976 according to
DIN standard. The material can be divided into Class 4.8, 8.8,
10.9, 12.9 for carbon steel; Stainless steel A2-70, A4-80 (304,
316), brass. Aluminum is also available. Size from M3 to M70, length from 100mm to 4000mm. Surface treatment
including: Plain, zinc plated, nickel plated, H. D. G., black,
dacromet, mechanical zinc plated.
The specification for stud bolt and threaded rod DIN975 DIN976
cover 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
ASTM A193 B8M Class 1 Stainless steel, AISI 316, carbide solution
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
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,
ASTM A193 B8S Stainless Steel, AISI 218, also known as Nitronic 60,
