Introduction

As a steel technology expert in mold steel, I would like to share my knowledge and insights on S136 mold steel. S136 mold steel is a widely used material in the mold making industry due to its excellent properties and performance. In this article, I will provide a comprehensive review of S136 mold steel, including its chemical composition, properties, applications, and pricing.

Chemical Composition of S136 Mold Steel

S136 mold steel is a type of stainless steel that contains high levels of chromium and nickel. Its chemical composition is as follows:

\n
• Carbon: 0.38-0.45%
\n
• Chromium: 12.0-13.5%
\n
• Nickel: 0.3-1.0%
\n
• Manganese: 0.8-1.0%
\n
• Molybdenum: 0.20-0.35%
\n
• Silicon: 0.2-0.4%
\n
• Phosphorus: 0.03% or less
\n
• Sulfur: 0.03% or less
\n

The high chromium content in S136 mold steel provides excellent corrosion resistance, while the nickel content enhances toughness and strength. The addition of molybdenum also improves the steel's toughness and resistance to corrosion and wear.
