Stainless Steel Seamless Tubing 316L
Stainless Steel Seamless Tubing 316L
316L has more element molybdenum (Mo) than 304, and its corrosion performance is better.
Nickel: Nickel is a high-quality corrosion-resistant raw material, which is the key element in 316L thin-wall stainless steel pipe, which can improve the compressive strength and ductility of steel, can improve the cutting performance, when the water content is high, can significantly change the process performance of the aluminum alloy steel, it can make the mechanism of high chromium steel change greatly. Then improve the corrosion resistance of stainless steel plate and its performance has been improved.
Manganese: The effect of manganese on ferrite is similar to nickel, but to be precise, the effect of manganese is not dependent on the production of ferrite, but on its ability to reduce the critical heat treatment rate of steel and improve the reliability of ferrite in water cooling. Manganese can improve the compressive strength of steel, can weaken and remove the negative effects of sulfur, can improve the cutting performance of steel, high alloy steel with a high manganese content (high manganese steel) has excellent wear resistance and other process properties.
Molybdenum: can significantly improve the cutting performance and thermal strength of steel, avoid quenching ductility, improve remanence and jiao jiao force.
