Heatreatment line

 Protection atmosphere: adopt 2oxygen probe, one monitor, one measure, guaranteethe stability ofthe atmosphere in the quenchingfurnace, effectively eliminate the decarbonizationphenomenon of the   product.Equipment equipped with low temperature treatment,product retained austenite content is significantlylower than the national standard value;

Product level:The microstructure of the product after heat treatment is controlled at 2-3level;The hardness uniformity is controlled at HRC0.8;Retained austenite is controlled below 15%;
