Medical-grade stainless steel is a group of corrosion-resistant stainless steel alloys, mainly 316L, 304, 420 and 410, made to meet strict standards for hygiene, strength and biocompatibility in medical devices and surgical instruments. It withstands body fluids and repeated sterilization, keeps a smooth, easy-to-clean surface, and complies with ASTM and ISO standards recognized by the FDA.

Sanmei Metal supplies these medical grades as coil, sheet and precision strip, cut to the size you need, with a mill test report for every order.

Features of Sanitary Stainless Steel

Excellent Corrosion Resistance

Medical-grade stainless steel must have outstanding corrosion resistance as it comes into contact with various chemical solutions and disinfectants in medical environments.

Exceptional Biocompatibility

Medical-grade stainless steel is non-toxic and non-allergenic to human tissues, ensuring patient safety.

High Strength and Wear Resistance

Medical instruments must endure mechanical stress and wear; thus, medical-grade stainless steel must have good mechanical properties.

Easy to Clean and Sterilize

Medical instruments require frequent cleaning and sterilization. Medical-grade stainless steel has a smooth surface that is easy to clean and sterilize.

Non-toxic and Safe

Medical-grade stainless steel does not release harmful substances, ensuring the health and safety of patients and healthcare personnel.

Compliance with International Standards

Medical-grade stainless steel must meet the stringent requirements of international standards such as ASTM, ISO, and FDA.

Types of Medical Grade Stainless Steel

Depending on the application, medical stainless steel can be categorized into Surgical Stainless Steel, Dental Stainless Steel, Medical Instrument Stainless Steel, Cardiovascular Stainless Steel and Biomedical Stainless Steel.
Medical-grade-stainless steel
01

Surgical Stainless Steel

Used for manufacturing surgical instruments, requiring high strength, corrosion resistance, good biocompatibility, non-toxicity, and good machinability.
Common suitable stainless steel grades:
316: Contains 2-3% molybdenum, improving pitting and crevice corrosion resistance, particularly in chloride environments. It is suitable for long-term implants in the human body.
316L: Similar to 316 but with lower carbon content (less than 0.03%), reducing the risk of carbide precipitation and improving corrosion resistance at welded joints.

dental stainless steel instruments
02

Dental Stainless Steel

Used for dental tools and implants, requiring wear resistance, corrosion resistance, strong biocompatibility, high strength, and maintaining appearance after prolonged use in the oral cavity.
Common suitable stainless steel grades:
304: Contains 18% chromium and 8% nickel, with good corrosion resistance and mechanical properties, often used in dental instruments and tools.
304L: Similar to 304 but with lower carbon content, reducing the risk of carbide precipitation during welding, making it more suitable for welded dental instruments.
420J1 and 420J2: Medium carbon martensitic stainless steels with high hardness and wear resistance, used for sharp dental instruments like curettes and scissors.

medical instrument stainless steel
03

Medical Instrument Stainless Steel

Used for precision medical instruments, requiring high strength and toughness, corrosion resistance, biocompatibility, high-temperature sterilization, and good machinability.
Common suitable stainless steel grades:
321: Adds titanium to 316 series, improving high-temperature resistance. It also has good corrosion resistance and biocompatibility, meeting the requirements for medical-grade materials. Its excellent mechanical properties ensure that equipment made from 321 can withstand various stresses in high-temperature environments.
410: High carbon martensitic stainless steel with high strength and moderate corrosion resistance, suitable for surgical instruments.
410S: Similar to 410 but with lower carbon content, improving weldability and reducing the risk of hardening and cracking during welding.
420J1 and 420J2: Used for medical instruments requiring high hardness and wear resistance, such as surgical knives and scissors.

cardiovascular stainless steel stent
04

Cardiovascular Stainless Steel

Used for cardiovascular stents and devices, requiring biocompatibility, corrosion resistance, high strength and toughness, and precision manufacturing.
Common suitable stainless steel grades:
316LVM (Vacuum Melted 316L): This grade is a standard material for cardiovascular devices. Vacuum melting improves material purity and consistency, enhancing biocompatibility and corrosion resistance. It is widely used in cardiovascular implants like stents and catheters.

biomedical stainless steel implant
05

Biomedical Stainless Steel

Used for various implants and medical devices, requiring high biocompatibility, strength, toughness, corrosion resistance, and good machinability and formability.
Common suitable stainless steel grades:
2205 (F60, F51): Duplex stainless steel with 22% chromium and 5% nickel, and molybdenum, offering excellent corrosion resistance and mechanical properties, particularly in chloride environments. Used for biomedical devices and implants.
2507: Super duplex stainless steel with higher chromium, nickel, and molybdenum content than 2205, providing better corrosion resistance and strength, suitable for more demanding biomedical environments.

Coating that lasts longer, matches and stays clean.

Three things we measure on our own production, each compared with typical market product.
PVD coating

Thicker PVD coating

0.30µm
Typical market coil: 0.21–0.27 µm. Ours is up to 28% thicker.
In plain terms: the coating takes longer to wear through, so the color lasts longer.
See the coating test
Color control

Consistent color

ΔE ≤ 2
Most suppliers give no color tolerance at all. Every coil of ours is held at ΔE 2 or less.
In plain terms: reorder next year or mix batches on one wall, and the panels still match.
See the color data
Anti-fingerprint

Fingerprint-resistant

215solvent rubs
The standard asks for 100 solvent rubs. Typical market anti-fingerprint coating failed at 70; ours lasted 215.
In plain terms: fingerprints wipe off, and the coating holds up to daily cleaning.
