Product Description

sncm439 peeled or turned Steel Round Bar

sncm439 steel grade is one kind of nickel chromium molybdenum alloy steel known for it's toughness and ability to attach high strength and hardness after quenching and tempering. sncm439 steel material is one steel grade in JIS standard. It's similar steel materials are aisi 4340, sae 4340, astm 4340, 40CrNiMoA, 34CrNiMo6 etc. It is one high alloy steel with high steel mechanical properties. As a steel factory, we can produce sncm439 Cold Drawn Steel Round Bar, sncm439 peeled steel Round Bar , sncm439 turned steel round bar, sncm439 ground and polished steel round bar, sncm439 Annealed Steel Bar, sncm439 Normalized Steel Bar, sncm439 Quenched And Tempered Steel Bar. We can also supply competitive price raw material sncm439 hot rolled steel round bar.


Steel bar peeling or turning is a kind of machining used to remove the imperfections on the hot rolled bars surface. It can also get more precision diameter tolerance and bright surface after peeling or turning. If grinding or polishing is added, the steel bars will be have very good surface roughness which can be directly used to produce components. sncm439 steel bar are usually heat treaded before direct usage especially sncm quenched and tempered steel bar. Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.
