BS 4360 Grade 43A Hot Rolled
BS 4360 Grade 43A Hot Rolled introduction
BS 4360 Grade 43A was withdrawn and superceded by BS EN 10025 S275. This grade is a popular low carbon steeel grade and is suitable for a large number of engineering applications. Its low price make it suitable for different applications such as building and machinery constructions when wear-resistant and high strength is not a requirement.
