What is ST15 steel grade?
ST15 is a grade of cold-rolled low-carbon steel plate, which belongs to the deep drawing grade steel in the German standard (DIN standard) or European standard (EN standard) system.
Is ST15 steel good quality?
In cold stamping, high appearance requirements and low load scenarios, ST15 steel is one of the preferred materials in the industry due to its excellent formability and surface quality.
Is ST15 mild steel?
ST15 steel is a low-carbon aluminum-killed steel that belongs to the German standard (DIN EN 10130) and is commonly used in cold processing fields such as stamping and drawing.
Is ST15 the same as SPCC?
ST15 is a grade of German DIN standard or European EN standard, which is a cold-rolled low-carbon steel. It has a higher elongation and is specially used for deep stamping, such as automobile body covers, high-precision deep-drawn parts (such as fuel tanks, complex shape shells); SPCC is a grade of Japanese JIS standard (JIS G 3141), which is also a cold-rolled low-carbon steel, suitable for general cold forming purposes, such as home appliance housings, general stamping parts, and structural parts.
What is the key difference between ST15 and CR3?
Both ST15 and CR3 are cold-rolled low-carbon steels, but they belong to different standard systems. ST15 belongs to the European EN standard (EN 10130) and is designed for high formability requirements, especially for complex deep-drawn parts; CR3 belongs to the Chinese GB standard (GB/T 5213) and is one of the common grades of domestic cold-rolled low-carbon steel.
