40Cr13
Higher hardness than 30Cr13 after quenching, used as cutting tools, nozzles, valve seats, valves, etc.
4Cr13 / 1.4031 is a high-carbon martensitic stainless steel known for its good hardness, wear resistance, and moderate corrosion resistance. It is commonly used in applications that require both mechanical strength and some level of corrosion resistance, such as knife blades, surgical instruments, kitchen tools, scissors, and cutting tools.

Supply size
Thickness: 0.04-25mm Thickness Tolerance: +/-0.005
Width: 4.6-2000mm Width Tolerance: +/-0.02
Length: coil type or it can be produced as customer requirements
Surface: DSM offers a variety of different surface treatments for stainless steel plates. There are1U, 1C, 1D, 1E, 2B, BA, No.4, TR, HL etc.
Inner Diameter: 300400500（Customized according to the customer's machine size）Outer diameter: The outer diameter range is determined based on the width of the material required by the customer and the maximum weight of a single trailer.
Edge: the edge of the steel strip is trimmed, and the burr height is 10% mm. If there are special requirements for the edge, it can be scraped.
