PRODUCT DETAILS

Product Description

Stainless steel is a corrosion-resistant alloy steel based on iron with alloy elements such as chromium (Cr), nickel (Ni), molybdenum (Mo), and titanium (Ti). The chromium content ≥10.5% is the key to its corrosion resistance. According to different organizational structures, it is mainly divided into five categories:
Austenitic stainless steel (such as 304, 316L): non-magnetic, good toughness, excellent corrosion resistance, and the most widely used;
Ferritic stainless steel (such as 430): magnetic, stress corrosion resistant, and low cost;
Martensitic stainless steel (such as 410, 420): can be strengthened by heat treatment, high hardness, and weak corrosion resistance;
Duplex stainless steel (such as 2205): austenite + ferrite dual-phase structure, with both strength and corrosion resistance;
Precipitation hardening stainless steel (such as 17-4PH): hardened by aging treatment, used in high-strength corrosion-resistant scenarios.
Appearance characteristics: The surface has a silvery white metallic luster and can be processed into glossy (2B), matte (No.4), mirror (8K), etc., or the texture can be changed through processes such as sandblasting and brushing.

Shipping Packaging

1. Sheet/Roll Packaging
Inner Packaging:
Plastic film or oil paper is used to prevent scratches and moisture (such as 2B surface stainless steel plate);
Precision sheets (such as mirror 8K) are separated by pearl cotton or corrugated paper to avoid friction.
Outer Packaging:
Fixed with wooden box or iron frame (to prevent shaking during transportation), tied with steel belt;
Label: brand, specification (thickness × width × length), surface treatment, furnace number.
