40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel A709 Gr 50 low alloy steel is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
