440 stainless steel from China Economic Steel Group is a martensitic grade with 16-18% chromium and approximately 1.0% carbon, delivering hardness up to 58HRC after heat treatment. This composition makes it one of the hardest stainless steels available, with superior wear resistance and corrosion resistance compared to standard austenitic grades like 304 or 316. The supplier offers it in coil, strip, plate, sheet, tube, pipe, flat, and bar forms to suit diverse industrial applications.
The material is magnetic and retains sharpness, making it a preferred choice for precision components, valve parts, pump shafts, and chemical processing equipment where standard grades lack required strength. Typical industry use includes cutlery, bearings, and turbine parts, while variants like 440A, 440B, 440C, and 440F cater to specific machining or performance needs. The carbon content range of 0.6% to 0.75% contributes to its high yield strength and toughness under impact.
Industries sourcing this grade include oil and gas, food processing, and precision engineering, where its balance of hardness, wear resistance, and corrosion resistance is critical. Buyers typically request it in annealed or heat-treated conditions, with surface finishes and tolerances tailored to end-use. Confirm with the supplier for available forms, dimensions, and heat treatment states, as these vary by order.

Before ordering, verify the exact grade variant (440A, B, C, or F) and its carbon content, as this directly impacts hardness and corrosion resistance. Request the supplier’s mill test certificates to confirm compliance with ASTM A276 or EN 10088-3 standards, and clarify whether the material is provided in annealed or pre-hardened condition.
Confirm logistics details such as lead time, which typically ranges from 20 to 45 days for stainless steel plates depending on thickness and quantity. Standard Incoterms for this supplier are likely FOB or CIF, with packaging in wooden crates or bundles to prevent damage. Payment terms often require a 30% deposit via TT, with the balance due before shipment.
For quality checks, perform visual inspections for surface defects, verify dimensions with calipers or micrometers, and conduct hardness testing (e.g., Rockwell C-scale) on a sample. Request a third-party inspection if the order is large, and ensure the supplier provides a packing list, commercial invoice, and bill of lading with HS code 7219.34 for 440 stainless steel plates.
