SUS444 Disk Stainless Steel Plates Mirror Gold 8.0*1500mm

SUS444 (00Cr18Mo2) is an ultra-low carbon nitrogen, 18% chromium and 2% molybdenum, ferritic stainless steel with high corrosion resistance. This steel is generally stabilized with niobium or titanium, which can avoid intergranular corrosion after welding. This steel grade is especially suitable for use in various water treatment devices.
SUS444 steel is a high-alloy ferritic stainless steel, compared with the commonly used steel SUS444:
1. The chromium content is about 1.0% higher, and the alloying element molybdenum (Mo) is added, so this steel has good resistance to pitting corrosion, crevice corrosion and stress corrosion, and its corrosion resistance is even better than SUS304 in some fields and SUS316.
2. Stabilizing elements such as titanium (Ti), niobium (Nb), and zirconium (Zr) are added, so this steel has good resistance to intergranular corrosion and high temperature oxidation.

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.
Other special surfaces: color plating, water ripple, etching, anti-fingerprint, etc.
