What is the equivalent of 1.2312 steel?

In the realm of tool steels, understanding the equivalent grades of 1.2312 steel can significantly aid professionals in selecting the right materials for their projects. 1.2312, also known as P20+S, is a widely recognized type of plastic mold steel designed to meet specific demands of machining and durability.

Properties of 1.2312 Steel

This steel grade is notable for its enhanced machinability due to the addition of sulfur (0.05-0.1%), which translates into substantial improvements in milling and drilling speeds—up to 30% and 300% increases, respectively. It is primarily alloyed with chromium, manganese, and molybdenum, which bolster its strength and overall performance in industrial applications.

Global Equivalent Grades

Identifying equivalents of 1.2312 steel across different standards can facilitate its application globally. Comparable grades include:

• DIN 1.2311
• AISI P20
• JIS SPV 235
• AS 4130

These equivalents may vary slightly in chemical composition and mechanical properties, so it is essential to evaluate each one based on the specific requirements of your application.
