12L14 COLD DRAWN STEEL BAR
Cold drawn 12L14 Y15Pb steel bar is a resulfurized and rephosphorized carbon steel. This grade is considered free machining, having excellent machinability due to its added sulfur, phosphorus, and lead. Due to its low carbon, this material has lower strength than other cold drawn grades
We also supply 12L14 cold drawn bar to various industries like aerospace, automotive, and more.
12L14 steel is a free cutting structural steel, similar in chemical composition to the domestic Y15Pb free cutting structural steel.
12L14 steel belongs to lead sulfur compound free cutting structural steel. Lead free cutting steel, lead to small elemental Yu Gangzhong metal particles distribution and not solid fusion in the steel, in the process of machining, produce strong friction between cutter and machined part, to lead in particles in molten steel exudates, lubrication effect and to improve the cutting performance of steel, the steel scraps and finely, reduce tool wear, prolong tool life in the end. Compared WITH LEAD-FREE STEEL, THE CUTTING PROPERTIES OF LEAD-FREE STEEL CAN BE IMPROVED BY 20 ~ 50%, WHILE THE MECHANICAL AND HEAT TREATMENT PROPERTIES OF LEAD-FREE STEEL REMAIN UNCHANGED, AND THE cold AND THERMAL WORKability and welDABILITY ARE NOT affected.
Production
Free cutting steel has been widely used to manufacture precision instrument parts, automobile parts, all kinds of machinery important parts. However, the contact fatigue of lead free cutting steel is low, so it is not suitable for gear, bearing and other parts that bear heavy fatigue stress load. The 12L14 tends to be replaced by it. The cutting performance is also excellent. It is suitable for more strict occasions where the 12L14steel cannot be used.
characteristic
1. Easy iron processing performance is good: the product has smooth cutting, excellent material, stable processing,
Good microstructure, stable chemical composition, small deviation, pure steel, not easy to damage the tool characteristics;
Extremely easy to cut in the lathe, tool life and production efficiency are increased by 40%;
2. Good electroplating performance: cutting is very easy; Can drill deep hole, milling deep groove, etc.; Processing efficiency
Bipu steel can be greatly improved; The electroplating performance of the product is good, can replace copper products, greatly reduce the cost of products;
3. Good smooth iron: the surface finish of the workpiece after processing by the car is good;
4. Environmental protection: in line with EU SGS environmental certification standards, and through the Swiss environmental certification.
Machinery and equipment: woodworking machinery, ceramic machinery, paper machinery, glass machinery, food machinery,
Construction machinery, plastic machinery, textile machinery, jack, hydraulic press, etc.; Electrical parts: motor shaft,
Fan shaft, sewing machine shaft, etc.; Furniture: especially export metal furniture, such as coffee tables, chairs, outdoor furniture;
Metal tools: garden tools, grill rack, screwdriver, security lock, etc. Hardware spare parts: such as guide rail,
Machine keys, nuts, screws, round nails, hex nails and a variety of different specifications of standard parts; Cars,
Motorcycle spare parts, etc.
