Silicon Manganese Steel Chemical Composition, Grade Chart, Tables and Documents

Silicon manganese steel is a material that is widely used in different industries and similarly has a strictly defined chemical composition that is the key to its properties. In the general case, only about 65-68% manganese is present in it, also there are 16-25% silicon and the smaller amounts of carbon, phosphorus, sulfur and the other elements. This fabrication presents exceptional grade of strength, hardness, and wear resistance. Consequently, it can be used to make cars components, construction tools, and railways need. The grade chart labels steel to silicon manganese according to its content and performance features for the best materials to be picked on a specific job. Comprehensive table and documents present specification of mechanical properties, heat treatment process to follow and manufacturing standard that could be met by the customers making it easy to use the product by its users in a diverse industrial sector

Silicon Manganese Steel Chemical Composition Table

The chemical composition of silicon-manganese steel of high precision is important for their special properties and broad use scopes. Usually, this constitutes a mixture of carbon (C), silicon (Si), manganese (Mn), sulfur (S) and phosphorus (P), with possible traces of others. Actual configuration is set on intended attributes and production details specification. As far as a regular composition goes, it includes about 0.5-0.7% of carbon, 1.5-2% of manganese, and 0.5-1.5% silicon, where sulfur and phosphorus content are regulated for enhancing the mechanical attributes of the composition. The balance of it being neither too soft nor too hard is precisely achieved to have the optimized strength, durability and resistance to the wear and corrosion.

Silicon Manganese Steel Composition Table
Element Typical Content (%) Main Role Property/Effect
Carbon (C) 0.10% - 0.30% Enhances hardness and strength Increases hardness and tensile strength
Silicon (Si) 0.50% - 2.00% Deoxidizer, enhances strength and hardenability Improves hardenability and strength
Manganese (Mn) 1.00% - 2.00% Enhances strength, hardenability, and toughness Improves strength, toughness, and hardenability
Phosphorus (P) Up to 0.035% Impurity, affects mechanical properties Can increase strength and hardness
Sulfur (S) Up to 0.035% Impurity, affects machinability Can decrease machinability, affects ductility
