Product Description Cold coil is made of hot rolled coil at room temperature and below the recrystallization temperature, including plate and coil, of which the sheet delivered is called steel plate, also known as box plate or plate; the long length and delivered in coil is called steel strip, also known as coil plate. Production process: Due to no heating, there are no pitting and scale defects in hot rolling. The surface quality is good and the surface finish is high. Moreover, the dimension precision of cold rolled products is high, and the properties and structure of products can meet some special requirements, such as electromagnetic properties, deep drawing properties, etc. Performance: mainly made of low carbon steel, with good cold bending and welding performance, as well as certain stamping performance. SPCC is commonly used cold rolled carbon steel sheet and steel strip. SPCC Specification Features of cold-rolled steel plate: 1, Cold rolled steel plate thickness more accurate, smooth surface, beautiful, but also has superior mechanical properties, especially machining performance. 2. The maximum thickness of cold-rolled steel plate is less than 0.1-- 8.0mm, such as the thickness of cold-rolled steel plate in most factories is less than 4.5mm;The minimum thickness and width are determined according to the equipment capacity and market demand of each plant. 3, cold rolled steel mill power, low rolling efficiency, and the rolling process in order to eliminate the work hardening have to carry out intermediate annealing, so the cost is higher, but cold rolled steel surface bright, good quality, can be used to process finished products, cold rolled steel is widely used.

Product introduction Stainless steel 304 and stainless steel 304L are also known as 1.4301 and 1.4307 respectively. 304 is the most versatile and widely used stainless steel. It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of 304 being 18% chromium and 8% nickel. 304 stainless steel is an austenitic grade that can be severely deep drawn. This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans. 304L is the low carbon version of 304. It is used in heavy gauge components for improved weldability. 304H, a high carbon content variant, is also available for use at high temperatures Possible Alternative Grades Grade Why it might be chosen instead of 304 301L A higher work hardening rate grade is required for certain roll formed or stretch formed components. 302HQ Lower work hardening rate is needed for cold forging of screws, bolts and rivets. 303 Higher machinability needed, and the lower corrosion resistance, formability and weldability are acceptable. 316 Higher resistance to pitting and crevice corrosion is required, in chloride environments 321 Better resistance to temperatures of around 600-900 C is needed 321 has higher hot strength. 3CR12 A lower cost is required, and the reduced corrosion resistance and resulting discolouration are acceptable. 430 A lower cost is required, and the reduced corrosion resistance and fabrication characteristics are acceptable.
