Chemical composition of creep resisting steels to BS EN 10302

 Introduction

BS EN 10302 is the material standard for creep resisting steels, nickel and cobalt alloys in bar, rod and flat product forms. Martensitic and austenitic steels are included. Most of these grades can also be classed as stainless steels by the definition given in BS EN 10088-1, which considers steels with minimum chromium (Cr) contents of 11.5% and maximum carbon (C) contents of 1.2% to be stainless steels. In BS EN 10088 however the primary purpose of the alloys is corrosion resistance, whereas in BS EN 10302 the elevated temperature strength and oxidation resistance are the main properties required of the steels listed here, in their intended applications.

The latest 2008 edition has some minor changes:

• Most Chromium and Nickel ranges are now quoted to only 1 decimal place compared to 2 in the previous edition
• The P and S contents for grade 1.4922 have been lowered
• There is one new grade 1.4951 a 310 type with a minimum Ni content

These changes are shown in bold in the table below.

BS EN 10095: CHEMICAL COMPOSITION OF STAINLESS STEELS

Introduction

BS EN 10095 is the material standard for heat resisting steels and nickel alloys. The chemical composition of the common grades of stainless steel covered in the standard are listed. Ferritic, austenitic and austenitic-ferritic (duplex) grades are included.

As an alternative to scanning down the list try the 'find' facility on your keyboard, using the 'Ctrl' and 'F' keys together. Type in the term you are looking for in the dialog box that then appears.

The data given is not intended to replace that shown in individual standards to which reference should always be made.
