Introduction

Grade 302 is a slightly higher carbon version than grade 304. It is widely found in strip and wire forms. It is a standard specification for chromium and chromium-nickel stainless steel sheet, plate, and strip used for pressure vessels and for general applications.


Composition

The chemical composition of grade 302 stainless steel is outlined in the following table.

Element Content (%)
Chromium, Cr 17-19
Nickel, Ni 8 - 10
Manganese, Mn 2
Silicon, Si 1.00
Carbon, C 0.15

Manufacturing Process

Grade 302 steel requires slow speeds, and high feeds will aid in overcoming this alloy's tendency to work harden. It is recommended that chip breakers are used on all tooling due to the occurrence of gummy chips. While welding grade 302, it is recommended that resistance or shielded fusion methods are used. The filler metals to be used are AWS E/ER308 or 312. Post weld annealing is performed when the chromium carbide needs to be dissolved so as to provide maximum resistance to inter-granular attack. Forging is ideally performed at these temperatures - 1149-1260°C (2100-2300°F). It is advisable not to forge below 927°C (1700°F). Forgings should be fully annealed after all operations so as to maintain full corrosion resistance.

Hot working requires uniform heating to 1149°C (2100°F) while cold working helps to increase the hardness of this material. Grade 302 is quite ductile and can be readily drawn, spun and upset. Cold working causes this alloy to gain magnetic properties, and hence post-fabrication annealing is required to recover maximum corrosion resistance and a non-magnetic condition. Annealing is performed between 1010 and 1121°C (1850 and 2050°F) with fast cooling so as to avoid precipitation of chromium carbides.


Applications

302 stainless steel is the earliest used medical metal material, with good corrosion resistance and high strength.

Surgical implants: 302 stainless steel is often used to make surgical implants, such as bone fixation nails, bone plates, etc. Its excellent corrosion resistance ensures that long-term use in the body will not cause corrosion, thereby ensuring the surgical effect and patient safety.

Medical devices: In the manufacture of medical devices, 302 stainless steel is often used to make surgical instruments, medical equipment components, etc. Its good mechanical properties and corrosion resistance make these instruments more reliable in use.

These applications of 302 stainless steel benefit from its excellent physical and chemical properties. 302 stainless steel has good corrosion resistance, high strength and moderate ductility, and can perform well in medical environments.
In addition, 302 stainless steel has good processing performance and is easy to manufacture various complex medical devices and implants.
