Is 420 stainless steel good for knives

Yes, 420 stainless steel is widely regarded as a good material for knives and cutlery, particularly for general-purpose applications. 420 steel is a martensitic stainless steel characterized by its hardenability and magnetic properties. This steel grade typically contains 12-14% chromium and a carbon content of no less than 0.15%, though in actual production, a carbon […]

The 420 stainless steel heat treatment guide

What is 420 stainless steel? 420 stainless steel is a prominent martensitic stainless steel, well-regarded for its hardenability and often classified as a stainless tool steel. It exhibits ferromagnetic properties. The heat treatment process for 420 stainless steel typically follows steps similar to those for carbon steel: austenitization, quenching, and tempering. Austenitizing The primary goal

H11 Tool Steel

A full guide of h11 tool steel heat treatment

H11 tool steel heat treatment’s purpose is to transform the soft, annealed microstructure, consisting mainly of ferrite and alloy carbides, into a hardened and tempered martensitic structure with beneficial carbides that provide the desired cutting or working properties. This multi-stage process typically involves preheating, hardening, quenching, and tempering. So, what is H11 tool steel? H11

42CrMo4 Steel

42CrMo4 QT-Quenching and tempering process for 42CrMo4 steel

The “QT” in 42CrMo4 QT stands for quenching and tempering. 42CrMo4 steel is designated as 1.7225 in the UNS system and is a widely used high-strength alloy steel. The equivalent grades of 42CrMo4 include: 42CrMo4 steel exhibits deep hardenability, excellent comprehensive mechanical properties, and a low level of significant temper brittleness. It is extensively used
