Weathering steel AS/NZS 1594 - HW350A

General description HW350A is a high phosphorous structural weathering steel with a minimum yield strength of 340MPa. Typical uses ‒ Railway rolling stock and storage hoppers / bins ‒ Architectural features Features & benefits ‒ Reduced atmospheric corrosion when used in the correct environments ‒ Guaranteed minimum strength levels ‒ Good toughness Warnings ‒ This material should be used in conjunction with the appropriate structural design and welding standards ‒ The weathering properties of this material is due to the formation of an impervious oxide layer through the use of alloy additions. Damage to this layer, or environmental conditions affecting the development of this layer, will impact on the effectiveness of the corrosion resistance. ‒ Colour retention across welds can be achieved by appropriate electrode selection. Welds may be susceptible to hot cracking ‒ Weathering steels are not recommended without further protection for buried or submerged situations or for applications exposed to concentrated industrial fumes or severe marine conditions ‒ Oxide staining of surrounding areas may occur due to run-off from this material ‒ Refer to BlueScope Technical Bulletin No. 26 for more information regarding the use of this material Australian and International standards AS/NZS 1594: 2002 AS/NZS 1365: 1996 ISO9001 Quality System certified
