Description

Abstract

This specification covers the chemical requirements for wrought stainless steels used for the manufacture of surgical instruments. Classes of stainless steels covered here are Class 3 (austenitic stainless steel), Class 4 (martensitic stainless steel), Class 5 (precipitation hardening stainless steel), and Class 6 (ferritic stainless steel). The data contained in this specification, such as typical hardness values, common heat treating cycles, and examples of selected stainless steels that have been used for surgical instruments, are provided for reference only. Mechanical property, heat treatment, hardness, and all other requirements except for chemical composition, are governed by the appropriate material standards as specified or as agreed upon between purchaser and supplier.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers the chemistry requirements for wrought stainless steels used for the manufacture of surgical instruments. The data contained in Tables 1- 4 of this specification, including typical hardness values, common heat treating cycles, and examples of selected stainless steels that have been used for surgical instruments, is provided for reference only. Mechanical property requirements, heat treating requirements, hardness requirements and all other requirements except chemistry are governed by the appropriate material standards as referenced below or as agreed upon between the purchaser and supplier.
