ASTM A519 4130 Mechanical Seamless Steel Pipes For Automobile Axle Housing
1. Description
ASTM A519 4130 is Mechanical alloy seamless steel pipe, carbon and manganese content is slightly lower than 4140, of which the important element free Cr (0.80-1.10) Mo (0.15-0.25), 4130 material physical properties are very strong, the price is relatively high, in addition, the annealing treatment, also determines its performance, customers according to their own use requirements, told us when placing an order
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.
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. Please refer to ASTM A519 table as below for grades.

About us
Customers specify the standard, size and length of seamless steel pipe, we make one-to-one production according to the order. The minimum order quantity is 2 tons per size. As it is customized, customers need to provide the steel grade (standard), outer diameter, wall thickness, length and demand of seamless steel pipe when inquiry. We will send you a quotation at a very good price right away.
