When to use heat treated carbon steel fasteners?
Lower strength, mild carbon steel structural bolts, per ASTM A307, can be used to fasten statically loaded structures with lightweight members. Heat-treated fasteners are also essential in engine, vehicle and hydraulic applications where bolts and fasteners are under high stresses.See all results for this questionWhen to heat treatment ASTM A53 grade B pipe?The welding seam for ERW welding processes in ASTM A53 Grade B pipe should be done heat treatment after welding to a min of 540 1000. Consequently, there is no untempered martensite remains, or use the other ways of non untempered martensite remains.See all results for this questionWhat is the definition of a threaded coupling?A 865 The definitions for threaded coupling, carbon steel and hot galvanized zinc coated welded and seamless, for the joints of the steel pipe. g.
