Thabiso Steel stands out as a top-notch manufacturer and supplier located in Cape Town, South Africa. They’ve built a solid reputation for providing high-performance industrial fasteners, particularly their Alloy Steel Gr B7 Bolts. Known for their quality, precision, and reliability, Thabiso Steel serves a diverse array of industries, including construction, petrochemical, and energy. The company excels at meeting the rigorous specifications of demanding projects while adhering to tight delivery timelines, ensuring that customers are satisfied both locally and internationally. Their Alloy Steel Gr B7 Bolts are crafted to meet strict industry standards, delivering impressive strength, durability, and exceptional resistance to pressure, temperature, and corrosion.
These bolts are made from chromium-molybdenum steel (AISI 4140/4142), which gives them remarkable hardness and tensile strength. Typically, they contain about 0.40% carbon, 0.75–1.00% chromium, and 0.15–0.25% molybdenum. After undergoing heat treatment to boost their performance, they achieve a minimum tensile strength of 125 ksi (860 MPa) and a yield strength of 105 ksi (724 MPa). They also demonstrate good elongation and reduction of area, which contributes to their toughness under stress. Alloy Steel Gr B7 Bolts are particularly well-suited for high-pressure and high-temperature settings, making them perfect for critical industrial applications.
