High -chromium (also known as wear -resistant steel ball) is a scientific ratio of all kinds of wear -resistant materials in Anhui Phoenix.Chromium ball wear resistance, reduce the crushing rate, and improve the toughness of high chromium balls. The high chromium ball production process produced by Anhui Phoenix has a national patented high chromium white mouth cast iron grinding ball., Referred to as high chromium balls.
High chromium standard
1. High-chromium ball quality index: chromium content ≥10.0%, carbon content between 1.80%-3.20%is called high chromium balls. National standards require high chromium ball hardness (HRC) must be ≥58 or more.AK ≥ 3.0J/，2, if this hardness high chromium ball must be high -temperature quenching+recovery (currently two types of high chromium quenching two types of oil quenching and wind quenching), such as detection hardness (HRC) below 54The following shows that the high chromium ball has not been quenched.2. Middle chromium ball quality index: 3.0%to 7.0%of chromium content, carbon content between 1.80%-3.20%is called medium chromium ball, impact value AK ≥ 2.0J/㎝2, national standard requirements medium chromiumBall hardness (HRC) must be above ≥47. To ensure that chromium balls in the quality of steel balls need to be treated with high temperature recovery (to achieve the purpose of eliminating casting stress), such as dark red on the surface of the steel ball indicatingFor example, the surface of the steel ball is still metal.3. Forging steel ball quality indicators: chromium content 0.1%to 0.5%(forging balls without chromium), carbon content below 1.0%and steel balls are made of high temperature forging, some forging steel ball surface hardness(HRC) Although it can reach ≥56 (only about 15㎜), the hardness of the heart is generally only more than 30 degrees due to the poor quenchtability of the steel ball material.Exercise treatment.
High chromium price
The price of high chromium balls is around 4000-6000 yuan.
