904L 444 Matte Stainless Steel Sheet Plate 0.5 - 5mm Thickness 1000 - 1500mm Width

We use pure smelted 904L and 444 stainless steel raw materials with complete material test reports and factory certificates. 904L grade contains low carbon and high molybdenum components, effectively resisting chloride ion erosion; 444 grade adds optimized titanium stabilization elements, with better stress corrosion resistance and structural stability. The steel plate has high tensile strength, strong impact resistance, good hardness uniformity, excellent flatness, no deformation, no warping and no bending under long-term load-bearing and outdoor placement. The whole plate has stable mechanical properties, not easy to break or damage during stamping, cutting and bending processing, greatly improving the yield rate of finished industrial parts.

The surface is treated with professional continuous mechanical matte finishing process, forming an even, delicate and smooth matte texture across the entire board surface. No mirror strong reflection, no dazzling glare, effectively improving on-site construction safety and equipment appearance grade. The surface has strong adhesion, no peeling, no fading, no scratches, with good wear resistance and friction resistance. The tight surface protective layer can effectively resist dust, oil stains and daily attachments, easy to clean and maintain without extra later maintenance cost. Batch production ensures consistent surface color and uniform texture, perfectly matching large-area industrial equipment assembly and outdoor overall project installation.

Conventional complete size in stock: thickness range from 0.5mm to 5mm, width range from 1000mm to 1500mm, with matched standard fixed lengths. The thickness tolerance is strictly controlled within the national standard error range, with smooth and burr-free cutting edges, neat plate corners and no edge collapse. We support free fixed-size slitting, fixed-width cutting, flat leveling and customized special-shaped processing according to customer drawings. Whether it is small-batch prototype trial production or large-batch engineering bulk orders, we can quickly match the required specifications, shorten delivery cycle and save procurement time cost for buyers.

This series of matte stainless steel sheets has far better rust resistance, acid resistance, alkali resistance, salt spray resistance and high temperature oxidation resistance than ordinary 201 and 304 stainless steel plates. It can stably work for a long time in coastal high-salt spray environment, chemical plant acid-base workshop, sewage treatment equipment, humid underground facilities and outdoor exposed structural parts. It will not rust, perforate, peel or discolor under long-term contact with chemical medium, moisture and salt fog. It has excellent weather resistance, adapting to extreme temperature difference changes, rainwater erosion and outdoor ultraviolet aging, with ultra-long service life and low later replacement cost.

904L and 444 matte stainless steel plates have good ductility, toughness and welding performance, fully compatible with all industrial processing technologies. It supports laser cutting, plasma cutting, cold bending, hot bending, stamping forming, argon arc welding, drilling, grinding and deep drawing. No cracking, no brittle fracture, no edge bursting during processing. It can be made into chemical tank inner lining, anti-corrosion equipment shell, outdoor engineering guardrail, mechanical equipment outer panel, pipeline supporting plate and other finished parts, with high processing efficiency and strong production adaptability for processing factories.

Widely used in chemical industry, petroleum, marine engineering, coastal infrastructure, water treatment equipment, environmental protection dust removal equipment, food machinery, pharmaceutical equipment, outdoor anti-corrosion engineering, mechanical manufacturing, electrical equipment shell, building anti-corrosion decorative structure and other high-standard anti-corrosion fields.

Sufficient spot inventory, stable batch supply, fast delivery speed. Professional waterproof paper, anti-scratch film and reinforced wooden frame packaging are adopted to prevent surface damage, plate deformation and moisture erosion during long-distance sea and land transportation. Complete inspection reports are provided to support third-party quality inspection, reliable one-stop industrial metal material supply service.
