making it widely used in oil & gas

AISI 4130 is a medium carbon, low alloy steel material specified in standard ASTM A29. AISI 4130 is a low-alloy steel known for its high strength, toughness, and good weldability, making it widely used in oil & gas, aerospace, and automotive industries.

25CrMo4 is a low-alloy chromium-molybdenum steel grade, similar to AISI 4130, and widely used in applications requiring high strength, good toughness, and resistance to wear and fatigue. It’s standardized under EN 10083-3 and used across industries like automotive, aerospace, pressure vessels, and oil & gas.
