High hardness, corrosion resistance, and cost optimization enable safe and reliable medical tools


In the medical industry, the performance of instrument materials directly affects patient safety and surgical results. Through material optimization and precision processing, DSM420J2 stainless steel significantly improves corrosion resistance while maintaining the high hardness of martensitic stainless steel, becoming a cost-effective solution for surgical, dental and disposable medical devices.


Why choose DSM420J2 for the medical industry?

  • Excellent hardness and wear resistance

The hardness can reach HRC 50+ after heat treatment, ensuring the sharpness and durability of surgical blades, orthopedic drills and other instruments.

Suitable for high-frequency use scenarios, such as dental instruments and surgical scissors, to reduce performance degradation caused by wear.


  • Optimized corrosion resistance

The special smelting process reduces the impurity content and pitting risk, which is better than the traditional 420J2.

The surface can be adapted to DLC coating, titanium nitride (TiN) and other treatments to further improve corrosion resistance and antibacterial properties.


  • Strict medical compliance

Complies with ISO 10993-5 biocompatibility standards for short-term contact devices.

FDA 510(k) & CE certification ensures material safety and traceability.


  • Significant cost-effectiveness

Compared to 316L stainless steel, the cost is reduced by 30%~40%, which is suitable for disposable devices or budget-sensitive purchases.

The mature precision stamping and etching processes support the efficient mass production of complex device structures.



Material properties, one step ahead

DSM420J2 is a martensitic stainless steel. Through optimized metallurgical control and purification process, it greatly improves corrosion resistance and processing stability while maintaining its hardness advantage.

Inner and outer diameter

Inner Diameter: 300, 400, 500( 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.

Note: The weight of a single trailer generally does not exceed 2 tons to ensure that the goods will not be damaged during transportation and moving.


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.


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.
