Product Description

ASTM A519 4130 Mechanical Tubes

ASME Sb519 Steel AISI 4130 Seamless Round Tubes

4130 Steel Introduce  

AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. The steel has good strength and toughness, weldability and machinability. 
AISI/SAE 4130 grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength. It shows good overall combinations of strength, toughness. and fatigue strength.

Standard:
EN 10216-2: 2014 Seamless steel tubes for pressure purposes. Non-alloy and alloy steel tubes with specified elevated temperature properties
EN 10305-1: 2010 Steel tubes for precision applications. Seamless cold drawn tubes.
EN 10297-1: 2003 Seamless circular steel tubes for mechanical and general engineering purposes. Non-alloy and alloy steel tubes.
