Alloy steel AISI 4130 is a multipurpose material known for solid properties of greatest strength, wear resistance, toughness among others. Its chemical composition greatly includes chromium and molybdenum, which can certainly harden and protect from corrosion. The combination of carbon and chromium in this steel type makes it ideal for the sectors requiring high tensile strength. For example, the industry deals with aerospace components, automotive parts, and even equipment for oil and gas industries. Represented by ASTM A519 Grade 4130, ASTM A29 Grade, and others for AISI 4130 class. In a simple form, its graph illustrates its common duties such as tensile strength, yield strength and elongation. Moreover, integration of field testing and material certificates into the process guarantees compliance with industry standards and specifications, making its integration possible into virtually any engineering project or product.
AISI 4130 alloy steel is one of the most versatile and widely applied materials due to its superior strength and toughness. The molecular composition consists carbon, manganese, phosphorus, sulfur, silicon, chromium, and iron at the primary level. The chart, pdf and table of grade AISI 4130 engineering usually contain specification as ASTM A322, ASTM A519, ASTM A646, ASTM A29, and AMS 6370. Its composition that gives the wide strength, great weldability, and superior corrosion resistance is the reason it is used in industries like aerospace, oil and gas.
