ASME SA193 Grade B16, ASME SA193 Grade B16 Bolt, Nuts, ASTM A193 Bolt Manufacturer in India – China Inconel Bolts Inc.

ASME SA193 Grade B16 is a high-strength 5 percent chromium ferritic steel used to manufacture bolts, studs, stud bolts, and other fasteners for bolting pressure vessels, valves, flanges, and fittings, particularly in the power generation industry. The ASTM A193 standard includes alloy and stainless steel bolting for pressure vessels, valves, flanges, and fittings used in high temperature or high-pressure applications, as well as other special applications. There are many grades covered, including ferritic steels and austenitic stainless steels with designations such as B5, B6, B7, B8, B8M, and so on.
