Weather Resistant High Strength Slainless Steel (WHSS), which has excelent comprehensive properties such as high corrosion resistance, high strength, high tensie stength, non-magnetism, good bio-compatibility and high-temperature resistance, is an advanced structured material developed by using nitrogen to replace the precious metal nickel.lts excelent performance is recogized worldwide as a cuting-edge erronmental fiendly material wth great development space and polertial.
High Strength Weather Resistant Stainless Steel Applications
Chemical Industry
Corrosion-resistant, high and low temperature, high-pressure tank valves, valve bodies, flanges, highly corrosion-resistant high-strength bolts, and piping components.
Defense Industry
Pressure-resistant, non-magnetic hull materials for deep-submergence submarines, aircraft carrier deck steel, non-magnetic hull materials for minesweepers, armor protection materials, aircraft engine blades, gun barrels, and high-temperature wear-resistant bearings.
Energy
In the energy sector, ultra-supercritical (USC) boilers with high efficiency and high parameters.
Ocean-going Ship
In the shipbuilding sector, piping systems for seawater systems.
Vehicles
New generation turbocharger housings and exhaust manifolds.
- WHSS Non-magnetic Oil Drill Drill Collar
- WHSS Steel For Ultra-supercritical Boilers
- WHSS High Performance Oil Pipeline
- WHSS Marine Military Series Products
A Wide Range of Applications
WHSS is widely applicable to the materials especially in petrochernical industry, miltary indusry,marine equipment industry,ultra-supercritical boiler pipeline etc.
A Great Variety of Product Lines
Compared with high-pressure metallurgy,while producing WHSS ingots, various WHSS castings, bars, pipes, pipe accessories, welding wires, etc. can be directly produced. This technology will greatly enrich the product variety of WHSS and expand its application fields.
The Outstanding Product Performances
This product has mechanical properties comperable to the 15-15HS series of high nitrogen materials from CARPENTER in the United States, but its corrosion resistance is higher than that of 15-15HS,especially in seawater corrosion environments and hydrogen sulfide corrosion ernvironments.
The pitting equivalent greater than 40; The ability to resist acdic media is equivalent to stainless steel such as 3l6LN, and the local corrosion resistance is significantly better than austenitc stainless sieel.
The maximum tensile stength can reach 2200MPa, and it also has good plasticity (12%), high toughness(above 25j), higher high-temprerature strength(above 500MPa at 700°C), and high creep resistance(above 150MPa at 650 °C).
