Wire Rod Corrosion resistance

316 and 317 stainless steel (317 stainless steel performance see below) is molybdenum stainless steel. 317 stainless steel molybdenum content is slightly higher in the 316 stainless steel due to the molybdenum steel, the steel's overall performance is better than 310 and 304 stainless steel, high temperature conditions, when the sulfuric acid concentration of less than 15% and 85% 316 stainless steel has a wide range of uses. 316 stainless steel also has good properties of chloride erosion, so it is usually used in marine environments.

316L stainless steel maximum carbon content of 0.03, can be used after welding can not be annealed and the need for maximum corrosion resistance in the use of

Corrosion resistance

Corrosion resistance is better than 304 stainless steel, in the pulp and paper production process has a good corrosion resistance. And 316 stainless steel is also resistant to erosion of marine and erosive industrial atmospheres.

Heat resistance

In the continuous use of 1600 degrees below the continuous use and below 1700 degrees, 316 stainless steel has good resistance to oxidation. In the range of 800-1575 degrees, it is best not to continuously use 316 stainless steel, but in the temperature range outside the continuous use of 316 stainless steel, the stainless steel has good heat resistance. 316L stainless steel resistance to carbide precipitation better than 316 stainless steel, available above the temperature range.

Heat treatment

Annealing at a temperature in the range of 1850 to 2050 degrees, then rapidly annealing, and then rapidly cooling. 316 stainless steel can not be superheated to harden.


316 stainless steel has good welding performance. All standard welding methods can be used for welding. Welding can be used according to the use of 316Cb, 316L or 309Cb stainless steel filler rod or welding electrodes. For optimum corrosion resistance, 316 stainless steel welded sections require post-weld annealing. If 316L stainless steel is used, no post-weld annealing is required.

Typical use

Equipment for pulp and papermaking Heat exchangers, dyeing equipment, film flushing equipment, pipelines, coastal areas Building materials for external use.

Domestic steel prices rose steadily. By the peripheral market during the National Day bad suppression, postganglionic opening of the steel and the period showed a relatively weak trend, intraday decline has increased, although the late rise, closing up, but the days of turnover did not heavy volume, The overall risk aversion is more obvious, is expected to short-term steel market to a relatively narrow range of relative weakness. The impact of the disk by the weak, the performance of the stock in the overall performance of the general, the main price of goods into a strong trend, the market is still strong trend, but the external suppression, amplitude is too small. For the performance of the capital market throughout the month, by the external market turmoil, the overall performance of steel is difficult to show bright, is expected to run more than a weak, for the spot steel market will be repressive factors exist. The spot steel market in October with the advantage of raw material prices rose to increase the cost of steel production costs, squeeze steel prices profit margins, making steel prices will increase the demand for the formation of the support of the spot market. According to the current Tangshan fine powder and the price of coke in Linfen area, the production cost of blank is about 2,100 yuan, plus the rolling cost and labor and other miscellaneous fees, steel profit margins have been squeezed quite obvious, and in the Environmental supervision continue to strictly control, steel enterprises in the first half of the case of significant profits, the late emergence of a significant price reduction to kill the market the probability is not, therefore, this has become the strongest support factor in the spot market.
