The redevelopment of a definite yield point phenomenon as a result of ageing can result in a renewed susceptibility to surface imperfections, such as stretcher strain marks (Lders Lines) and fluting when the steel is formed. To avoid these ad

Rotation of stock, by using the oldest material first, is important. Effective roller levelling immediately prior to fabrication can achieve reasonable freedom from st

Zinc-coated and zinc-iron alloy-coated steel sheet less than 600 mm wide, slit from wide sheet, will be

The purchaser shall indicate on the order which method of specifying thickness is required. In the event

41、that the purchaser does not indicate any preference, the thickness as a combination of the base metal and coating will be provided. Annex A describes the requirements for specifying the thickness of the base metal alone.5 Conditions of manufacture5.1 SteelmakingUnless otherwise agreed by the interes
