Themba Nickel Alloys, a reputable manufacturer and supplier located in Cape Town, Cape Town, specializes in high-quality Hastelloy Bars designed to offer outstanding corrosion resistance, strength, and durability in tough industrial settings. Crafted with precision and in line with international quality standards, these bars are perfect for applications that face aggressive chemicals, extreme temperatures, and both oxidizing and reducing environments. Themba Nickel Alloys guarantees excellent metallurgical consistency, a superb surface finish, and precise dimensions, making their Hastelloy Bars ideal for critical components in industries like chemical processing, petrochemical, marine, and power generation, where reliable and long-lasting performance is essential.
Hastelloy Bars are mainly made up of nickel, molybdenum, and chromium, with varying amounts of iron and tungsten depending on the specific grade (like C22, C276, or B2). This alloy is known for its remarkable resistance to pitting, crevice corrosion, and both strong oxidizing and reducing agents. The bars boast a tensile strength ranging from 690 to 785 MPa, a yield strength of 275 to 355 MPa, and an elongation of 40 to 45%. They maintain their mechanical stability and toughness even at high temperatures, offering excellent weldability, formability, and resistance to stress-corrosion cracking, making them perfect for heavy-duty and high-performance industrial applications.
