How to properly weld 304 stainless steel pipes

图片
Correct heat treatment can eliminate residual welding stress without affecting the corrosion resistance of the coating. The method is:   1.       Welded components of stainless steel plates with large order or high rigidity to be heat treated.   2.       The heat treatment should be carried out after the bottom welding is completed, and the internal and surface quality of the bait seam are all qualified, and the temperature should not exceed 400 degrees.   3.       The post-weld treatment at this temperature can reduce the residual stress by about 40%. This will not affect the turbidity resistance of the clad stainless steel.   4.       After the above heat treatment is completed, the isolation layer and the clad stainless steel plate can be welded. After the cladding is welded, no heat treatment is required.   HCADTO Stainless Steel Co., Ltd.   the Stainless...

Characteristics of 316 stainless steel plate

图片
Features: Due to the addition of Mo, the   316 stainless steel plate  has excellent corrosion resistance, atmospheric corrosion resistance and high temperature strength, and can be used under harsh conditions; excellent work hardening (non-magnetic); excellent high-temperature strength; non-magnetic in solid solution state ; Cold-rolled products have good gloss and beautiful appearance; compared with 304 stainless steel, the price is higher. 316 stainless steel is greatly improved in corrosion resistance and high temperature strength due to the addition of Mo element, and the high temperature resistance can reach 1200-1300 degrees, which can be used under harsh conditions. Uses: Seawater equipment, chemical, dye, paper, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts. HCADTO Stainless Steel Co., Ltd.   the Stainless   Steel   Division of ADTO GROUP, specializes in manufacturing s...

Why is the 304 stainless steel plate magnetic?

图片
People often use magnets to attract  stainless steel plates  to verify their pros and cons and their authenticity. If they do not attract and have no magnetism, the y think they are good  and genuine; those who attract magnets are considered counterfeit. In fact, this is an extremely one-sided, unrealistic and wrong identification method. There are many kinds of stainless steel plates, which can be divided into several categories according to the organizational structure at room temperature: 1.       Austenitic type: such as 304, 321, 316, 310, etc.; 2.       Martensite or ferrite type: such as 430, 420, 410, etc.; Among them, the austenite type is non-magnetic or weakly magnetic, and the martensite or ferrite is magnetic. Most of the stainless steel plates usually used as decorative tube sheets are austenitic 304 materials, which are generally non-magnetic or weakly magnetic, but may also a ppear magnetic due to fluctuati...
