ASTM A778 Stainless Steel Welded Pipe

ASTM A778 Stainless Steel Pipe is used in low to moderate temperature and is for unannealed, Welded Stainless Pipe. TP304L and TP316L are the most common Grades.

The pipe manufactured per ASTM A778 can be supplied as Cold Drawn or Hot Rolled. And can also be provided threaded, beveled and plain end. The material cannot be annealed or heat treated for hardening.

ASTM A790 / A790M

Seamless and welded duplex stainless steel pipe

Covers ferritic/austenitic stainless steel pipe, specifically designed for stress corrosion resistance. Includes comprehensive mechanical and nondestructive testing requirements.

ASTM A240 / SA240

ASTM A240 - Generally deals with chromium stainless steel and chromium-nickel stainless steel and is the most widely used standard for Sheets, Plates, Strips, and Coils of stainless steel.

This standard covers several grades of stainless steel and due to its outstanding properties like corrosion resistance, strength, toughness, and formability it is commonly used in Pressure Vessels, Food Processing, Chemical Processing and the Petrochemical Industry.

ASTM A276 / A276

ASTM A276 Scope: This specification covers hot-finished or cold-finished bars except bars for reforging. It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in stainless steels. The bars shall be furnished in one of the following conditions: Condition A in which the bars are annealed, Condition H in which the bars are hardened and tempered at a relative temperature, Condition T in which the bars are hardened and tempered at a relatively high temperature, Condition S in which the bars are strain hardened or relatively light cold worked, and Condition B in which the bars are relatively severe cold worked. The material shall be subjected to a mechanical test to determine its tensile strength, yield strength, elongation, and Brinell Hardness.
