We are a professional manufacturer of ASTM 12L13, we can provide the third party inspection report and datasheet of ASTM 12L13 as round bar, square bar, flat steel and so on. Please send the inquiry to us if you are if you are interested in ASTM 12L13. We will serve you with honesty, integrity, and professional. The detail data as below follow:
Steel Grade: ASTM 12L13| UNS G12134
CHEMICAL COMPOSITION(ASTM 12L13):
C(％) : ≤0.13
Mn(％) : 0.70～1.00
P(％)≤: 0.07～0.12
S(％)≤: 0.24～0.33
Other(％) : Pb0.15～0.35
Remark(ASTM 12L13):
1, The standard of cold wording bar is ASTMA 108-1999.
2, The special quality standard of hot wording bar is ASTMA 576-90b(2000).
3, In order to prevent the Si reduce steel machinability, the Si content of free cutting is low than ordinary steel, the ω(Si) of 1108,1109 and 1110 are under 0.10%, the rest are under 0.20%.
4, In order to improve the machinability, it can be added microscale Bi,Ca,Se,Te after supply and demand both sides agreed.
Introduction Free cutting steel (ASTM 12L13)
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 (ASTM 12L13)
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.
