A519 1045 Seamless Pipes Manufacturing: ASTM A519 1045 seamless carbon steel pipe is usually manufactured by hot working steel, and if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions and pr

DIN 17175 St35.8 alloy steel pipe is just a big class,and it has many classifivations. We mainly produce DIN 17175 ST35.8 seamless pipes,DIN 17175 ST45.8 seamless steel pipes, and 10CrMo910 alloy steel pipes.

ASTM A519 standard covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. The steel used in the mechanical tubing may be cast in ingots or may be strand cast.

4140 steel pipe has high strength, hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperatures.
