Stainless steel are the following: Model 301 - scalability for molding products. It can also be rapidly hardened by mechanical processing. Good weldability. Abrasion resistance and fatigue strength than 304 stainless steel. 302 Model 304 with corrosion resistance, due to relatively high carbon intensity and therefore better. Model 303 - by adding a small amount of sulfur and phosphorus to more than 304 cutting. Model 304- general model; that is 18/8 stainless steel. GB grades 0Cr18Ni9. Model 309 - 304 - better temperature resistance. Model 316 - After 304, the second most widely used of steel, mainly used in the food industry and surgical equipment, add molybdenum to obtain a special corrosion-resistant structure. Than the 304 because it has better resistance to chloride corrosion and thus as "marine steel" to use. SS316 is often used to fuel recovery. 18/10 grade stainless steel is usually in line with the application level Model 321 in addition to the added titanium elements to reduce the risk of material other than the corrosion of the weld performance similar to 304. 400 Series - ferritic and martensitic stainless steel type 408 - good heat resistance, low corrosion resistance, 11% Cr, 8% of Ni. Model 409 - the cheapest model (BAR), commonly used as automobile exhaust pipe, is a ferritic stainless steel (chrome steel). Domestic stainless steel demand can not imagine, no matter what industry, sanitary industry Hao, Ye Hao electronics industry, including kitchenware, automotive, medical, batteries, glasses, etc., there will need to use the welding of stainless steel products, domestic more extensive use of the welding, TIG welding, but out of the product is easily deformed, not beautiful, subsequent polishing is too much trouble, there are requirements for workers, not only inefficient, over time the cost is relatively high, it is now home to said laser welding machine has been slowly seize the market, more and more manufacturers certainly, whether it is from the speed, efficiency or cost savings have certain advantages, some people might think laser welding machine price is high, but as a long-term plan to only need to invest only once, a few years down the light can save tens of thousands of labor costs, but also not the other, and the high efficiency of laser welding, scrap rate, can be automated production and subsequent processing simply, not Precision product, then no need to deal with, if you wanted to rob in front of peers, then you can think about the process of change. As long hesitation that greatly reduce the time to make money, but peers have to spend in the future you want to have laser welding outstanding advantages and relatively difficult.
