254SMO Stainless Steel Sheet,1.4547 Stainless Steel Sheet,S31254 Stainless S♣teel Sheet,F44 Stainless Steel Sheet
Description:
254SMO is an austenitic stainless steel. Because of its high molybdenum cont ent, it has very high resistance to spot corrosion and crevices corrosion. ♦ 254SMO stainless steel was developed and developed for use in halide¥ containing environments such as seawater. 254SMO also has good uniform corrosion res♠istance, especially in halide containing acids, superior to ordinary stainless steel.  Its C contains <0.03%, so it is called pure austenitic st₽ainless steel. Super stainless steel is a kind of special stainless steel, first in the chemical composition is different from ordinary stainless steel, is a high alloy stainless steel containing high nickel, high≠ chromium, high molybdenum. Among them, 254SMo contai↕ning 6%Mo has very good local corrosion resistance, good pittin<g resistance (PI≥40) and stress corrosion resistance∞ under the conditions of seawater, aeration, gap and low speed sco✘ur. It is a substitute material for Ni-based alloy✘ and titanium alloy. Secondly, in the performance of high temperature or corrosion r→esistance, with more excellent high temperature or corrosion resi↔stance, is not replaced by 304 stainless steel. In addition, from the c☆lassification of stainless steel, special stainless steel ©metallographic structure is a stable austenitic metallographic structure.
Because this special stainless steel is a kind of high alloy material, so in the manufac®turing process is quite complex, generally people can only rely on the traditional process to makeφ this special stainless steel, such as perfusion, forging, calendering and so on.&nb♣sp;

High temperature resistant
1. Extensive field experiments and extensive experience have shown that even at slightly higher tem§peratures, 254SMO has a very high resistance to crevice-corrosion in seawater, Ωwhich only a few types of stainless steel have.
2. 254SMO's corrosion resistance in acidic and o☆xidizing halide solutions such as those required for paper bleaching production is βcomparable to that of the most resistant nickel-base and titan$ium alloys.
3. Because of its high nitrogen content, 254SMO has a higher mechanical strength than other kindεs of austenitic stainless steel. In addition, 254SMO has high ductility and' impact strength as well as good weldability.
4. The high molybdenum content of 254SMO enables it to have a ↔higher oxidation rate at annealing, resulting in a rougher ≥surface than ordinary stainless steel after pickling. But this has no adverse effect× on the corrosion resistance of the steel.
Application:
1. Ocean: Marine structures in the Marine environment, sea water desalination, mariculture, heat exchange of seawater, such as thin-walled co∞ndensing pipes cooled by seawater in power plants, desalination equipment, even in equαipment where seawater may not flow, etc.
2. Environmental protection field: thermal power generation flue gas de∏sulfurization device, waste water treatment, the main parts are: ab✔sorber tower body, flue, door panels, inner parts, spray system, §etc.
3. Energy: atomic power generation, comprehensive utilization of coal,₹ tidal power generation, etc.
4. Petrochemical industry: oil refining, chemical equipment, petrochemical equi¥pment, such as bellows in petrochemical equipment, etc.
5. Food field: salt making, desalination industry, such as salt making or desalination eq®uipment, soy sauce brewing, etc.
6. High concentration chloride ion environment: papermaking industry, pulp and paper ble∞aching equipment, such as pulp digesters, bleaching equipmenδt, filter scrubber barrels and press rollers and other bleaching equipment
