254SMO Stainless Steel Plate,1.4547 Stainless Steel Plate,S31254 Stainless Steel Plate,F44 Stainless Steel Plate
Description:
254SMO is an austenitic stainless steel. Because of its ♠high molybdenum content, it has very high resistance to spot corrosion and crevices coΩrrosion. 254SMO stainless steel was developed and developed for us®e in halide containing environments such as seawater. &n☆bsp;254SMO also has good uniform corrosion resistan←ce, especially in halide containing acids, superior to ordinary₽ stainless steel. Its C contains <0.03%, so it is called pure austeni≈tic stainless steel. Super stainless steel is a kind o<f special stainless steel, first in the chemical composition i×s different from ordinary stainless steel, is a high alloy stain>less steel containing high nickel, high chromium, high molybdenum. Among them, 254↓SMo containing 6%Mo has very good local corrosion resistance, good pitting resistance (PI≥40) and stress corrosion resistance under the conditions of ←seawater, aeration, gap and low speed scour. It is a substitute material for Ni-based ÷alloy and titanium alloy. Secondly, in the performa♥nce of high temperature or corrosion resistance, with more excellent high temperature or corrosio♦n resistance, is not replaced by 304 stainless steel. In addition, from the classi&fication of stainless steel, special stainless steel metallographi£c structure is a stable austenitic metallographic structure.
Because this special stainless steel is a kind of high alloy material, so in th>e manufacturing process is quite complex, generally people can only rely on the traditional process to make this special stainless steel, such asπ perfusion, forging, calendering and so on.

High temperature resistant
1. Extensive field experiments and extensive experien ce have shown that even at slightly higher temperatures, 254SMO has a ver↑y high resistance to crevice-corrosion in seawater, which only a f"ew types of stainless steel have.
2. 254SMO's corrosion resistance in acidic and oxid'izing halide solutions such as those required for paper bleaching productionπ is comparable to that of the most resistant nickel-base and titanium alloys.
3. Because of its high nitrogen content, 254SMO has a hΩigher mechanical strength than other kinds of austenitic stainless sδteel. In addition, 254SMO has high ductility and impact st rength as well as good weldability.
4. The high molybdenum content of 254SMO enables it to have a higherπ oxidation rate at annealing, resulting in a rougher s✘urface than ordinary stainless steel after pickling. But Ωthis has no adverse effect on the corrosion resistance of the steel.
Application:
1. Ocean: Marine structures in the Marine environment, seawater dγesalination, mariculture, heat exchange of seawater, such as thin-walled condensing pipes cooled by≠ seawater in power plants, desalination equipment, even& in equipment where seawater may not flow, etc.
2. Environmental protection field: thermal power genera$tion flue gas desulfurization device, waste water treatment≥, the main parts are: absorber tower body, flue, door panels, inner parts, spray÷ system, etc.
3. Energy: atomic power generation, comprehensive utilizatδion of coal, tidal power generation, etc.
4. Petrochemical industry: oil refining, chemical equipment, petrochemica®l equipment, such as bellows in petrochemical equipment, etc.
5. Food field: salt making, desalination industry, such as salt ma king or desalination equipment, soy sauce brewing, ₽etc.
6. High concentration chloride ion environment: papermaking industry, pulp and paper bleachi♥ng equipment, such as pulp digesters, bleaching equipment, filter s€crubber barrels and press rollers and other bleaching equipment
