Cold Rolled 409 Stainless Steel Sheet

Cold Rolled 409 Stainless Steel Sheet

409 Stainless Steel is a stabilized ferritic stainless steel that provides improved oxidation and corrosion resistance compared to carbon steel. Ease of fabrication combined with its corrosion resistance and economy have significantly broadened its utilization in automotive exhaust and other non-automotive applications. ASTM A240 defines three (3) sub categories of Type 409 stainless steel; UNS S40910, UNS S40920 and UNS S40930. Each of these designations has a slightly different Ti or Nb stabilization requirement. Each of these compositions can be supplied as UNS S40900 unless the purchaser specifically identifies a specific composition. It is produced with enhanced formability characteristics known as “High Performance” or “Ultra Form” in the industry.

mild steel coil suppliers
Cold Rolled Mild Steel Coil

Mild steel is also known as plain-carbon steel, is the most common form of steel as it provides material properties that are acceptable for many applications. Mild contains approximately 0.05–0.15% carbon making it malleable and ductile. Mild steel has a relatively low tensile strength, but it is cheap and easy to form; surface hardness can be increased through carburizing.

Non oriented electrical steel present excellent magnetic properties in all directions, being a perfect material for various applications, such as electrical motors and compressors. High permeability grades has a higher magnetic induction guaranteed value when compared to regular NGO.

Corrugated galvanized iron sheet,steel supplier
CGCC DX51D Corrugated Roofing Sheets Galvanized Iron Roof Sheet

The coated steel sheet we make into our roof cladding are produced in accordance with a strict series of quality standards by leading suppliers, giving us traceability and quality control. The durability of this roof cladding material is dependent on the galvanised and protective coatings applied to roofing substrate and fenicing substrate. As a roofing sheets material, steel has long been used in building and has the added benefit of being recyclable. To produce our high quality pre-coated roof cladding sheets, a system of multi-layer coatings is applied to the zinc-coated high tensile steel strip and then oven-cured to ensure optimum adhesion. This gives roofing sheets with excellent corrosion resistance and climatic protection together with abrasion resistance and a strong structure.

Colour Coated Steel Sheets
Hot Dipped Pre Painted Corrugated Sheet

Pre-paint steel is a bare metal substrate or corrosion resistant substrate that has had paint applied to both sides through a constant coil coating process, which produces an unchanging paint finish. The metal is relaxed, cleaned, and chemically treated during the procedure. Depending on product specifications, one or both sides may then be primed and coated, oven cured, and rewound for best performance and durability.

301 stainless steel sheet suppliers
Cold Rolled 301 Stainless Steel Sheet

301 Stainless Steel is an austenitic chromium-nickel stainless steel that provides high strength and good ductility when cold worked. The chromium and nickel contents are lowered to increase the cold work-hardening rate. This generates higher tensile strengths when cold rolled with a lower loss of ductility than with Types 302 and 304. The grade is essentially non-magnetic when annealed. When cold worked, it becomes slightly more magnetic than other standard austenitic stainless steels. WanJuan Steel is your stainless steel distributor for 301 Stainless Steel.
