There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than ASTM A709 carbon steel plate, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.
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 ASTM A709 carbon steel plate 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.
Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our ASTM A709 carbon steel plate products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
The company has always been adhering to the business philosophy of "integrity-based, responsibility oriented, quality first, reputation first" and is committed to building a world-class steel materials and service provider. We will continue to work hard to carry forward the enterprise tenet of "quality is the life of the enterprise, survival by quality, development by reputation", and become an enterprise with strong vitality! We always keep it in mind that profit is important to enterprises. But what counts more is social responsibility.
