Product Description

Product Description

Product Introduction

Stainless steel plate is an alloy sheet made of iron as the matrix, with chromium (Cr) content ≥ 10.5% and carbon (C) content ≤ 1.2% added. It can be made by adding nickel, molybdenum, manganese, titanium and other alloy elements according to demand.

It is an indispensable basic material in modern industry and daily life. Its core characteristics stem from a dense, stable, and self-healing chromium rich passivation film formed on the surface, which can effectively isolate air, moisture, and corrosive media, thereby endowing the steel plate with excellent corrosion resistance (not absolutely rust free, but may rust in extreme corrosive environments or after the passivation film is damaged). 

The product combines the high strength and ease of processing of metal materials, as well as better weather resistance and hygiene than ordinary carbon steel. It can be produced through different processes such as hot rolling and cold rolling to meet the needs of different scenarios. It is widely used in industrial production, building decoration, daily necessities, special fields and other scenarios. With complete specifications and strong customization, it can meet various personalized usage needs.

 

Product Features

1.Excellent corrosion resistance: Surface chromium-rich passivation film resists atmosphere, rainwater, acid/alkali and salt spray. Different grades suit various corrosive environments, with a much longer service life than carbon steel or coated plates.
2.Outstanding mechanical performance: High strength, good toughness, impact resistance; heat treatable for higher hardness. Good ductility and formability support bending, stamping, stretching and welding, ideal for complex structures and lightweight design.
3.Diverse surface textures: Multiple finishes available (hot-rolled matte, 2B, BA mirror, No.4 brushed, etched, colored), balancing practicality and decoration to meet different appearance needs.
4.Hygienic and easy to clean: Smooth, non-porous surface inhibits bacteria growth, non-toxic and compliant with food/medical standards. Simple daily cleaning reduces long-term maintenance costs.
5.Wide temperature resistance: Stable performance from -270℃ to 800℃, resisting high-temperature oxidation and low-temperature brittleness, suitable for extreme conditions like high-temperature equipment and cryogenic storage.
6.Eco-friendly and recyclable: 100% recyclable with high residual value; clean production meets green standards, reducing resource waste and lifecycle costs.
7.Flexible customization: Customizable thickness (0.2mm to hundreds of mm), width, length, surface treatment and material grades to meet personalized industry needs.

Product advantages

1.Excellent cost-effectiveness: Slightly higher initial cost, but lower long-term maintenance costs due to superior corrosion resistance and long service life; high recyclability ensures favorable lifecycle cost.

2.Wide application adaptability: Different grades/processes/specifications fit various environments (indoor, coastal, chemical, high/low temperature), covering industrial and daily scenarios.

3.Good processability: Easy to weld, bend, stamp and cut; stable forming effect without cracking/deformation, suitable for complex structures.

4.Reliable and stable quality: Mature production, precise dimensions, uniform performance; self-healing passivation film extends service life.

5.High compliance for premium use: Meets food, medical and environmental standards; safe and non-toxic for high-end scenarios.
