The American Society for Testing and Materials (ASTM) is a standards organization that develops and publishes standards for materials, products, systems, and services. Both organizations develop standards for steel products. However, AISI’s standards focus on the manufacturing of steel while ASTM’s standards focus on the testing and quality of steel products.
How does 4140 weld?
4140 is low-alloy steel that contains chromium, molybdenum, and manganese. The alloy has good weldability and can be welded using any welding process. However, the alloy should be preheated before welding to prevent cracking. 4140 can also be joined by brazing and soldering. The AISI code for 4140 steel is 4130.
