Barra de acero inoxidable AISI 316L

316/316L Stainless Steel Bar

material brand: 022Cr17Ni12Mo2

The characteristics of

1) the appearance of cold-rolled products is bright and beautiful;

2) due to the addition of Mo, the corrosion resistance, especially the pitting resistance, is excellent;

3) excellent high temperature strength

4) excellent work hardenability (weak magnetism after processing)

5) no magnetism in solid solution state;

6) compared with 304 stainless steel, the price is higher. [1]

use

Characteristics: 316 stainless steel is the second steel after 304, which is the most widely used, mainly used in food industry and surgical equipment. Due to the addition of Mo, its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, which can be used under harsh conditions. Excellent work hardenability (no magnetism).

316l stainless steel round steel is a type of stainless steel containing molybdenum, because the steel contains molybdenum, the overall performance of the steel is better than 310 and 304 stainless steel, high temperature conditions, when the concentration of sulfuric acid is less than 15% or more than 85%, has a wide range of USES. 316l stainless steel round steel also has good resistance to chloride corrosion, so it is usually used in Marine environment.

316l stainless steel round steel has a maximum carbon content of 0.03, which can be used for corrosion resistance where welding cannot be annealed and maximum corrosion resistance is required

The corrosion resistance of 304 stainless steel is better than that of 304 stainless steel. And 316l stainless steel round steel also resistant to ocean and erosion of the industrial atmosphere.

Heat resistance

316l stainless steel round steel has good oxidation resistance for intermittent use under 1600 ° c and continuous use under 700 ° c. In the 800-1575 degree range, it is best not to continuous action. However, the continuous use of 316L stainless steel outside the temperature range, the stainless steel has good heat resistance. The carbide resistance of 316l stainless steel round steel is better than that of 316 stainless steel.

Heat treatment

Solution annealing is performed at temperatures ranging from 1010 to 1150 degrees, followed by rapid cooling. 316L stainless steel cannot be hardened by overheating.

welding

316l stainless steel round steel has good welding performance. All standard welding methods are available for welding. According to the purpose, 316Cb, 316L or 309Cb stainless steel filler bar or electrode can be used for welding. In order to obtain the best corrosion resistance, the welding section of 316l stainless steel round steel needs to be annealed after welding. If 316l stainless steel round steel is used, post-welding annealing treatment is not required.

The 2205 grade steel is one of the most widely used ferritic and austenitic duplex stainless steel. The standard of this grade of steel has been refined over the years creating a versatile and strong product. It is has an excellent corrosion resistance (including in seawater), it is weldable by all standard methods, and has a high heat resistance.
