SUS444 (00Cr18Mo2) is a ferritic stainless steel with ultra-low carbon and nitrogen content, 18% chromium and 2% molybdenum, and high corrosion resistance.The yield strength of 444 is equivalent to 1.5 times of carbon steel and 6 times of fiberglass steel. It has outstanding advantages in shock resistance, snow resistance, wind pressure resistance and impact resistance. SUS444 ferritic stainless steel has high thermal conductivity, about 130% ~ 150% of Cr-Ni austenitic stainless steel, which is very suitable for heat exchange purposes. Small thermal expansion coefficient, the small unit is only 60% ~ 70% of chromium-nickel Olympic stainless steel, very suitable for hot expansion, cold shrinkage, thermal cycle conditions. The steel has good plasticity and toughness and is suitable for drawing, rolling forming and stamping manufacturing. Especially the application of corrosion resistance is the most excellent, in the high chloride medium corrosion resistance is better than ordinary ferrite stainless steel and Olympic stainless steel, generally do not produce chloride stress corrosion cracking. When Ti and Mo elements are added, the resistance to pore and crevice corrosion is improved. The steel can be welded by the method of welding ordinary stainless steel. This kind of steel is especially suitable for food processing equipment, heat exchanger, water heater tank, water storage tank, solar energy collection panel, etc.
444 Stainless steel sheet Price in China ,Manufacturer of 444 Stainless Steel sheet
444 steel belongs to high alloy ferritic stainless steel, compared with the commonly used steel SUS430:1. The chromium content is about 1.0% high, and the alloying element molybdenum (Mo) is added, so the steel has good resistance to pitting corrosion, crevices corrosion, stress corrosion ability, its corrosion resistance in some areas even better than SUS304 and SUS316. 2. Add titanium (Ti), niobium (Nb), zirconium (Zr) and other stabilized elements, so the steel has good intergranular corrosion resistance and high temperature oxidation resistance. The old brand is 00CR18MO2, the new brand is 019CR19MO2NB1Ï , the uniform digital code is S11972 (GB/T 20878-2007)
This is the most cost effective grade of steel. So the 444 Stainless Steel Sheet Price is lower compared to other grades of stainless steels and all metallic products in general. There are different versions of the material with low carbon and high carbon content. The low carbon version, 444 sheets are very good for welding applications as they have less carbide precipitation and less localized corrosion.

1D -- The surface has discontinuous granular shape, also known as fog surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling. 2D - A slightly silvery white colour. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling. 2B -- Silver white with better gloss and flatness than a 2D surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling. Ba - Excellent surface gloss, high reflectivity, like a mirror surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling. No.3 -- Good gloss, coarse grain surface. Processing technology: polishing and tempering rolling for 2D or 2B with 100~120 abrasive materials (JIS R6002). No.4 -- Good gloss, fine lines on the surface. Processing process: polishing and tempering rolling for 2D or 2B with 150~180 abrasive materials (JIS R6002). HL -- Silver grey with hair streaks. Processing technology: 2D products or 2B products with appropriate granularity of abrasive materials for polishing the surface is a continuous abrasive grain. MIRRO -- Specular. Processing technology: 2D products or 2B products with appropriate granularity of the grinding material grinding and polishing to the mirror effect.
