Material Types & Performance
Martensitic Steel Strip

• High yield strength and excellent toughness

• Tensile strength: 1500–2000 MPa

Our martensitic materials are developed and heat-treated according to customer requirements for hardness and uniformity, achieving both high dimensional precision and strong load-bearing capacity.
Flatness And Straightness:
With years of production experience and well-established processes, our martensitic steel strips achieve transverse flatness of ＜ 1 μm/mm and straightness of ≤ 3 mm / 5 m, meeting the strict requirements for saw blades, cutting blades, and other precision products.
