With a strong commitment to customer satisfaction, quick delivery, and solid technical support, Thabiso Steel has built a reputation as a dependable partner in South Africa’s expanding industrial and construction sectors.
The Alloy Steel Gr 2HM Washers are crafted from chromium-molybdenum alloy steel, which gives them remarkable strength, toughness, and wear resistance. Their composition features elements like carbon (0.35–0.45%), manganese (0.60–0.90%), chromium (0.40–0.70%), and molybdenum (0.15–0.25%). These washers boast high tensile strength (up to 100 ksi), impressive fatigue resistance, and a hardness range of 22–32 HRC. Thanks to these mechanical properties, they excel in high-pressure, high-temperature, and high-load applications, maintaining their integrity even in harsh conditions where standard washers might struggle.
