420 Tool Steel: Properties, Applications, and Supply
What is 420 tool steel?
420 tool steel, also known as AISI 420, W.Nr. 1.4021, and X20Cr13, is a martensitic stainless steel grade that combines good corrosion resistance with high strength after heat treatment. When properly quenched and tempered, it can reach hardness levels around 50 HRC, making it a reliable choice for parts requiring wear resistance, durability, and performance in mildly corrosive environments. Nifty Alloys is a 420 tool steel supplier providing certified, fully traceable material in multiple forms for customers in the UAE, the wider Middle East, and global export markets in line with international standards.
What is +QT800?
QT800 is a steel grade that has undergone quenching and tempering, characterized by its high strength, toughness, and resistance to wear. The term "QT" refers to Quenched and Tempered, whereas "800" signifies the typical tensile strength, which is around 800 MPa.
QT800 is commonly utilized in sectors where durability, resistance to fatigue, and mechanical strength are of utmost importance.
