310s stainless steel industrial pipe in China
According to the rough calculation, China's annual use of iron ore for 2.1 billion tons, of which 1.3 million tons of their own production, imports 700 million tons; but in terms of quality, China's iron ore production of iron ore is only 30% -40 %, While foreign imports of iron ore iron content of 62%.
In other words, if the iron content, we import volume reached 50%. 316 stainless steel containing molybdenum and low carbon content, in the ocean and chemical industry in the anti-pitting corrosion resistance is much better than 304 stainless steel! (316L low carbon, 316N nitrogen high strength, 316F stainless steel with high sulfur content, easy to cut stainless steel.
310s stainless steel industrial pipe: the main features are: high temperature, the general use of the boiler, the car exhaust pipe. Other performance in general.
1, ferritic stainless steel. Contains 12% to 30% chromium. Its corrosion resistance, toughness and weldability with the increase in chromium content increased resistance to chloride stress corrosion resistance is better than other types of stainless steel.
2, austenitic stainless steel. Containing more than 18% chromium, also contains about 8% of nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Comprehensive performance is good, can withstand a variety of media corrosion.
3, austenitic - ferritic duplex stainless steel. Both the advantages of austenitic and ferritic stainless steel, and has a superplasticity.
4, martensitic stainless steel. High strength, but poor plasticity and weldability.
