Stainless Steel 301 and 301LN Chequered Plates are widely used austenitic stainless steels known for their high strength, excellent corrosion resistance, and superior forming properties. These chequered plates, also referred to as diamond plates or tread plates, feature a raised pattern that provides improved slip resistance, making them ideal for flooring, transportation, and industrial applications.
SS 301 (UNS S30100 / Werkstoff Nr. 1.4310) and SS 301LN (UNS S30153) plates meet ASTM A240 / ASME SA240 specifications and are offered in hot-rolled and cold-rolled finishes, with options for polished, brushed, and designer surface finishes.

Key Highlights:
301LN has lower carbon and added nitrogen, improving weldability, toughness, and cryogenic strength.
301 provides high tensile strength after cold working and retains good ductility.
