ER307LSi and SUS307 is the same wire?
In fact, there is no 307 stainless steel grade, but the stainless steel wire grade has 307, that is, ER307300 series: chromium - nickel austenitic stainless steel 301: good ductility, used for molding products. It can also be hardened rapidly by mechanical processing. Weldability is good. Wear resistance and fatigue strength is better than 304 stainless steel. 302: corrosion resistance with 304, due to the relatively high carbon content and therefore better strength. 303: through the addition of a small amount of sulfur, phosphorus to make it easier to cut and process than the 304. 304: general-purpose models; that is, 18 / 8 stainless steel. Products such as: corrosion-resistant containers, cutlery, furniture, railings, medical equipment. The standard composition is 18% chromium and 8% nickel. For non-magnetic, can not be heat-treated to change the metallurgical structure of the stainless steel. GB grade 0Cr18Ni9. 304L: the same characteristics as 304, but low carbon, so more corrosion-resistant, easy to heat-treat, but the mechanical properties of the poorer welding and not easy to heat-treat the product. 304N: the same characteristics as 304 is a nitrogen-containing stainless steel, nitrogen is to improve the strength of the steel. 309: Compared with 304 has better temperature resistance, temperature resistance up to 980 ° C. 309S: with a large amount of chromium, nickel, so heat-resistant, good oxidation resistance, products such as: heat exchangers, boiler components, jet engines. 310: high-temperature oxidation resistance is excellent, the maximum operating temperature of 1,200 ° C. 316: after 304, the second most widely used steel, mainly used in the food industry, watches and jewelry, The addition of molybdenum gives it a special structure that resists corrosion. It is also used as a "marine steel" due to its better resistance to chloride corrosion than 304, while SS316 is commonly used in nuclear fuel recovery units. 18/10 grade stainless steel is also commonly used in this application. 316L: Low carbon and therefore more resistant to corrosion, easy to heat treat, for products such as chemical processing equipment, nuclear power generators, refrigerant storage lees. 316L: Low carbon and therefore more resistant to corrosion, easy to heat treat, products such as chemical processing equipment, nuclear power generators, refrigerant storage lees. 321: Similar properties to 304 except that the addition of titanium reduces the risk of corrosion in weld seams. 347: The addition of the stabilizing element niobium makes it suitable for welding aerospace parts and chemical equipment.
