With a strong focus on quality and customer satisfaction, Thabiso Steel provides durable, high-performance solutions designed to meet the needs of various industries. Their cutting-edge manufacturing facilities and commitment to innovation ensure a steady supply, competitive pricing, and dependable service. The Alloy Steel Grade 12 Coil exemplifies the company’s dedication to quality, boasting exceptional strength, corrosion resistance, and long-lasting performance in critical applications.
Typically, Alloy Steel Grade 12 Coil features a well-balanced mix of chromium (about 1.0–1.5%), molybdenum (0.4–0.65%), and low carbon content (around 0.05–0.15%), which boosts its strength and resistance to oxidation. This steel showcases impressive mechanical properties, including a tensile strength ranging from 415 to 585 MPa and a yield strength of approximately 205 MPa, with an elongation of around 30%. It also offers excellent weldability and can withstand high-temperature environments, making it perfect for applications that demand strength under pressure. Its creep resistance and hardness make it a great choice for extended use in tough conditions.
