Product Details

SUS444 is an  ultra-low carbon nitrogen, 18% chromium and 2% molybdenum, high corrosion  resistant ferrite stainless steel. The steel is usually stabilized by niobium  or titanium, which can avoid the intergranular corrosion after welding. The  steel is especially suitable for various water treatment devices.

  • The density is low, the usable area increases.

  • Good thermal conductivity, easy to dissipate heat.

  • Less thermal expansion and less welding deformation.

 

Product Description

SUS444 Stainless Steel characteristics:

SUS444 steel is  a high alloy ferritic stainless steel. Compared with the commonly used steel  type SUS430. High chromium content is about 1.0%, and add the molybdenum alloy  element, therefore the steel has good resistance to pitting corrosion, crevice  corrosion, stress corrosion, the corrosion resistant ability in some areas even  better than the SUS304 and SUS316.

Added titanium,  niobium, zirconium and stable chemical element, therefore the steel has good  resistance to interstitial corrosion and high temperature oxidation resistance.

Performance:

  • SUS444 has extremely low carbon  and nitrogen impurity elements.

  • SUS444 added molybdenum  elements to improve the resistance to pitting.

  • SUS444 added niobium or  titanium with stabilizing effect.

Corrosion resistance

  • Resistance to chloride ion stress corrosion cracking.

  • The corrosion resistance of the chloride ion point is better than SUS304.

  • The corrosion resistance of the chloride ion point is equivalent to  that of SUS316L.

  • There is no intergranular corrosion tendency after welding.

SUS444 Application

  • The yield strength of SUS444 is  equivalent to 1.5 times of carbon steel, 6 times of FRP, and excellent  performance for shock resistance, snow resistance, wind pressure and impact  resistance.

  • SUS444 ferrite stainless steel  has a high thermal conductivity, about 130%~150% of chromium nickel austenitic  stainless steel, which is very suitable for heat exchange.

  • The thermal expansion  coefficient is small, the small team is only chromium nickel austenitic  stainless steel 60%~70%, very suitable for hot rise, cold shrink, has the heat  circulation condition to use.

  • The steel has a good  plasticity, good toughness, suitable for stretching, rolling and stamping. In  particular, stress - resistant corrosion is the best. Corrosion resistance in  high chloride media is better than that of ordinary ferrite stainless steel and  austenitic stainless steel.

  • After adding the Ni, Ti, Mo and  other elements, the performance of the corrosion resistance and crevice  corrosion is improved, and the steel can be welded by welding common stainless  steel. The steel is especially suitable for food processing equipment, heat  exchanger, water heater tank, solar energy collection panel, etc.
