Custom 455 stainless steel suppliers and exporters in India.

we are Custom 455 Stainless steel suppliers in India. Custom 455 stainless resists staining in normal air atmospheres, and shows no corrosion in fresh water. Tests in 5% salt spray at 95°F (35°C) and in 5% ferric chloride at room temperature have demonstrated good resistance to pitting and rusting.

Laboratory tests in a variety of mild chemical environments have shown that the level of general corrosion resistance is superior to that of the 12% chromium steels (Type 410) and approaches that of the 17% chromium steels (Type 430). In most tests, there was no significant effect of aging temperature on corrosion resistance. Hydrogen embrittlement tests in 5% acetic acid saturated with H2S at room temperature show the same degree of susceptibility as other high-strength martensitic stainless steels.

Custom 455 stainless steel is a high-strength alloy known for its exceptional toughness, corrosion resistance, and versatility in various demanding applications. Developed specifically for medical and aerospace industries, Custom 455 offers a unique blend of properties that make it a preferred choice for critical components and structural parts.

In medical applications, Custom 455 stainless steel is extensively used in the manufacturing of surgical instruments and medical devices. Its biocompatibility, combined with its strength and corrosion resistance, ensures reliability and longevity in implants and surgical tools. The material’s ability to withstand sterilization processes further enhances its suitability for medical use.
