S 18-0-1 Steel Grade: The Preferred Choice for Heavy Machinery and Equipment

S 18-0-1 steel grade is a high-strength low-alloy (HSLA) steel that is primarily used in heavy machinery and equipment. It is known for its exceptional mechanical properties, corrosion resistance, and ability to withstand high temperatures.

The mechanical properties of S 18-0-1 steel grade are as follows:
– Tensile strength: 900-1100 MPa
– Yield strength: 800-900 MPa
– Elongation: 10-15% (in 50 mm)
– Hardness: 250-300 HB

The chemical composition of S 18-0-1 steel grade is as follows:
– Carbon (C): 0.16-0.22%
– Silicon (Si): 0.20-0.50%
– Manganese (Mn): 1.00-1.50%
– Phosphorus (P): max 0.030%
– Sulfur (S): max 0.020%
– Chromium (Cr): 0.90-1.20%
– Nickel (Ni): 0.20-0.40%

These specific mechanical properties and chemical composition make S 18-0-1 steel grade ideal for heavy machinery and equipment as it provides excellent strength and durability while maintaining corrosion resistance. It can withstand heavy loads, high temperatures, and harsh environments, making it a preferred choice for applications where reliability and longevity are crucial.
