High Strength Steel Plate is also known for its atmospheric corrosion resistance, the degradation inflicted to materials through exposure to air-borne pollutants. It is the maximum stress that a material can withstand while being stretched or pulled before breaking. In ductile materials the ultimate tensile strength can be higher, whereas in brittle materials the ultimate tensile strength is close to the yield point. High tensile steel sheets for automobiles are the fastest growing material in today\'s automobile industry and the key material when it comes to vehicle mass reduction.
High tensile stainless steel plate in order to enhance passenger safety and vehicle performance by reducing the weight of vehicles has become the top priority for today\'s automotive industry. They tend to have higher tensile strength compared with mild steels and duplex stainless steels have higher tensile strengths than austenitic steels. High tensile aluminium plate are used in numbers of everyday applications where strength and durability are important , from planes to trains, buses to trucks and even some of the world\'s tallest skyscrapers.
