Introduction Free cutting steel (9SMn28)
Free cutting steel is a kind of alloy steel that adds a certain amount of one or more sulfur, phosphorus, lead, calcium, selenium, tellurium and other free cutting elements in steel to improve its machinability. With the automation, speed and precision of cutting process, it is very important for steel to have good machinability. This kind of steel is mainly used for machining on automatic cutting machine tools, so it is also a special steel.
Characteristic (9SMn28)
1.: the product has good processing performance and smooth cutting, material quality, processing stability, microstructure, chemical composition and stability, small deviation, the purity of steel net, low inclusion content, is not easy to damage the tool features; easily in lathe cutting, tool life and production efficiency are increased by 40%;
2. electroplating performance: cutting is very easy; drilling deep hole, deep groove milling; machining efficiency of conventional steel can greatly improve the performance of the product; electroplating, can replace copper products, greatly reduce the cost of product;
3. good finish: the surface finish of the workpiece after being processed by car is good.
4. environmental protection: comply with the EU SGS environmental certification standards, and through the Swiss environmental certification. Products can export machinery and equipment: woodworking machinery, ceramic machinery, papermaking machinery, glass machinery, food machinery, building machinery, plastic machinery, textile machinery, Jack, hydraulic press and so on.
