What steel materials are SECC, SGCC, SPCC, SPHC and SPTE?

Commonly used steel plate materials: SPCC (cold-rolled plate), SPHC (hot-rolled plate), SECC (electro-galvanized plate), SGCC (hot-dip galvanized plate), SPTE (tin-plated steel plate, commonly known as tinplate). Common Japanese brands in general and mechanical structural steel plates:
1. Ordinary structural steel in Japanese steel (JIS series) grades mainly consists of three parts
The first part represents the material, such as: S (Steel) represents steel, F (Ferrum) represents iron;
The second part represents different shapes, types and uses, such as P (Plate) for plate, T (Tube) for tube, K (Kogu) for tool, U - special purpose, W - wire, wire, C - casting, F —Forgings;
The third part uses numbers to indicate the serial number or the lower limit of the strength value of the steel or steel product. Some brands also have suffixes such as A, B, C and other letters added to the numerical serial number to indicate different quality levels, types or thicknesses. For example: SS400 - the first S represents steel, the second S represents "structure", 400 is the lower limit tensile strength of 400MPa, and the overall represents ordinary structural steel with a tensile strength of 400MPa.
After the main structure of the grade (the first, second and third parts), the suffix symbols of the steel shape, manufacturing method and heat treatment can be added as needed. 2. Description of main brands:
SPHC - The first S is the abbreviation of Steel, P is the abbreviation of Plate, H is the abbreviation of Heat, and C is the abbreviation of Commercial. The overall representation generally uses hot-rolled steel plates and steel strips.
SPHD——represents hot-rolled steel plates and strips for stamping.
SPHE——represents hot-rolled steel plates and strips for deep drawing.
SPCC - represents generally used cold-rolled carbon steel sheets and strips, equivalent to China's Q195-215A grade. The third letter C is the abbreviation of Cold. When it is necessary to ensure the tensile test, add T at the end of the grade to indicate SPCCT.
SPCD - represents cold-rolled carbon steel sheets and strips for stamping, equivalent to China's 08AL (13237) high-quality carbon structural steel.
SPCE - represents cold-rolled carbon steel sheets and strips for deep drawing, equivalent to China's 08AL (5213) deep drawing steel. When non-timeliness needs to be ensured, add N to the end of the grade to indicate SPCEN. Quenching and tempering codes of cold-rolled carbon steel sheets and steel strips: annealed state is A, standard quenching and tempering is S, 1/8 hardness is 8, 1/4 hardness is 4, 1/2 hardness is 2, and hardness is 1. Surface processing code: D for matte finish rolling and B for bright finish rolling. For example, SPCC-SD represents standard quenched and tempered, matte finish rolling, generally used cold-rolled carbon sheets. Another example is SPCCT-SB, which represents cold-rolled carbon sheets with standard tempering and bright processing, requiring guaranteed mechanical properties.
