The hardenability of 12CrNi3 advanced carburized carbon steel is higher, annealing is more difficult, generally adopt tempering treatment, make the hardness reduced to <35HRC, to meet the cutting process.As a result of non-carburized surface without protection treatment (such as plating copper, brush anti-seepage paint, etc.), so the need for high temperature tempering after carburization, reduce the hardness, easy to cut off the carburized

Steel can be classified as carbon steel, high-strength low-alloy (HSLA) steel, heat-treated carbon steel, and heat-treated constructional alloy steel. Structural steel under the prolonged influence of operational factors such as pressure, temperature, cyclic loads, radiation, and the environment can lead to embrittlement as a result of thermal
What is low alloy structural steel - Meetyou CarbideDec 14, 2019 · Low alloy structural steel refers to the alloy structural steel with total alloy composition less than 5%. The carbon content of this kind of steel is similar to that of low carbon steel, and it is mainly strengthened by a small amount of alloy elements to improve toughness and weldability.alloy steel 12crni3, alloy steel 12crni3 Suppliers and S imilar steel grade & equivalent steel materials :Product Sales Information:Material 12crni3 steel round bar Size Diameter:20mm-1000mm Length:500mm-6000mm Origin place Made In China Delivery Condition Hot rolled,cold drawn,forged Surface require Black,grinding,bright,polish Heat treatment Quenched,Tempered,annealed Packing seaworthy packing ,wooden case ,carton,woven bag or at
