ASTM A519 Mechanical Seamless Steel Pipes For Automobile Equipments And Steel Structures
1. Description
We are specialized in exporting all kinds of ASTM A519 seamless steel tubes for machinery. These mechanical pipes are made of carbon steel and alloy steel by cold drawing or hot rolling. The chemical composition and physical properties are strictly controlled during the production of steel pipe to ensure that the customer's use, the tolerance of outer diameter and wall thickness can fully meet the standard requirements. The steel pipe surface can be sprayed, painted, oiled and passivated according to the customer's requirements. There are many ways to pack products, such as bare packing, simple packing and wooden box packing. Refer to ASTM A519 table as below for specific grades. At present, the most major export grades are: 1010, 1020, 1035, 1045, 4130, 4140 . Customers choose according to their own actual needs. ASTM A519 tubes is used to manufacture seamless steel pipes for containers, equipment, pipe fittings and steel structures, automobile pipes, medium and low pressure boiler pipes, liquid pipes and electric heater pipes.
