ASTM A335 Alloy Steel Seamless Pipes

Alloy Steel contains substantial quantities of elements other than carbon like chromium, silicon, nickel, manganese, molybdenum, tungsten, vanadium as well as limited amounts of other commonly accepted elements like sulphur, manganese, silicon & phosphorous. Addition of these alloying elements is usually done for purpose of increasing hardness, strength as well as chemical resistance of the end product.

Notes for Bend Test:	For pipe whose diameter exceeds NPS 25 and whose diameter to wall thickness ratio is 7.0 or less shall be subjected to the bend test instead of the flattening test.
	Other pipe whose diameter equals or exceeds NPS 10 may be given the bend test in place of the flattening test subject to the approval of the purchaser.
	The bend test specimens shall be bent at room temperature through 180 without cracking on the outside of the bent portion.
	The inside diameter of the bend shall be 1 inch [25 mm].
