ASTM A193 Coating Carbon Steel 4.8 8.8 All Thread Rod bolts and Nuts

Description:

Dacromet Coating Carbon Steel Alloy Steel B7​ ASTM A193 Stud Bolt Full Threaded Rod with ASTM A194 Heavy Hex Nuts are commonly used in offshore flatform, oil and gas. With dacromet 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.

Below are some common ASTM A193 specifications:
