From the heart of Hamilton’s industrial landscape, Latham Steel has built a reputation for sourcing and supplying robust materials for demanding applications. We are proud to offer the distinguished ASME SA 387 Grade 5 Class 1 & 2 sheets and plates, a product line that embodies our commitment to strength and reliability. This material is specifically engineered to withstand high temperatures and corrosive environments, making it a cornerstone for critical projects across New Zealand and beyond, where failure is not an option and performance is paramount.
The strength of this material lies in its precise composition and mechanical properties. It is a chromium-molybdenum alloy steel, with these elements providing excellent resistance to oxidation and corrosion, particularly at elevated temperatures. The steel is designed for high tensile strength and good ductility, even under stress in hot conditions. The “Class 1” designation indicates a normalized heat treatment, while “Class 2” is normalized and tempered, offering slightly different mechanical property balances to suit specific design requirements and service conditions for pressure vessels.
