What Is a Stainless Steel Sheet?

The surface of the stainless steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that does not rust easily, but it is not absolutely rust-free. Stainless steel plates are steel plates that are resistant to corrosion by weak media such as atmosphere, steam and water, while acid-resistant steel plates are those that are resistant to corrosion by chemically aggressive media such as acid, alkali, and salt. Stainless steel plates have been around since the beginning of the 20th century and have a history of more than a century.

JIS Stainless steel plate JIS

The common structural steel in Japanese steel (JIS series) grades is mainly composed 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. For example, P (Plate) indicates a plate, T (Tube) indicates a tube, and K (Kogu) indicates a tool; the third part indicates a characteristic number, which is generally the lowest tensile strength. For example: SS400-the first S means Steel, the second S means "Structure", 400 is the lower limit tensile strength of 400MPa, and the general means of ordinary structural steel with a tensile strength of 400MPa.

SPHC Stainless steel plate SPHC

SPHCThe first S is the abbreviation of Steel, P is the abbreviation of Plate, H is the abbreviation of Hot Heat, and C is the abbreviation of Commercial Commercial. Generally, it means hot rolled steel plate and steel strip.

SPHD Stainless steel plate SPHD

SPHDIndicates hot-rolled steel plate and steel strip for stamping.

SPHE Stainless steel plate SPHE

SPHEIndicates hot-rolled steel sheet and steel strip for deep drawing.

SPCC Stainless steel plate SPCC

SPCCIndicates that cold-rolled carbon steel sheets and strips are generally used, which is equivalent to the middle Q195A grade. The third letter C is an abbreviation for Cold. When it is necessary to ensure the tensile test, add T at the end of the grade for SPCCT.

SPCD Stainless steel plate SPCD

SPCDIndicates cold-rolled carbon steel sheet and steel strip for stamping, which is equivalent to China 08AL (13237) high-quality carbon structural steel.

SPCE Stainless steel plate SPCE

SPCEIndicates cold-rolled carbon steel sheet and steel strip for deep drawing, which is equivalent to China 08AL (5213) deep drawing steel. To ensure non-timeliness, add N to the end of the grade for SPCEN. Cold-rolled carbon steel sheet and strip quenching and tempering code: Annealing state is A, standard tempering is S, 1/8 hard is 8, 1/4 hard is 4, 1/2 hard is 2, and hard is 1. Surface processing code: matte finish rolling is D, bright finish rolling is B. SPCC-SD stands for cold-rolled carbon sheet for general quenching and tempering and matte finish rolling. Another example is SPCCT-SB, which refers to cold-rolled carbon sheet that requires standard hardening and bright processing and requires mechanical properties.

The JIS mechanical structure steel grade is expressed as: S + carbon content + letter code (C, CK), where the carbon content is represented by the middle value × 100, the letter C: represents carbon K: represents carburizing steel. For example, the carbon junction coil S20C has a carbon content of 0.18-0.23%. Third, China and Japan silicon steel sheet brand expression method.

Stainless steel plate China

(1) Representation method of cold-rolled non-oriented silicon steel strip (sheet): DW + iron loss value (at a frequency of 50HZ, the waveform has a sinusoidal magnetic induction peak value of 1.5T per unit weight iron loss value) + 100 times the thickness value 100 times. For example, DW470-50 represents a cold rolled non-oriented silicon steel with an iron loss value of 4.7w / kg and a thickness of 0.5mm. The new model is now 50W470.

(2) Representation method of cold-rolled oriented silicon steel strip (sheet): DQ + iron loss value (at a frequency of 50HZ, the waveform is a sine wave, and the magnetic induction peak value is 1.7T per unit weight iron loss value) 100 times the thickness value 100 Times. Sometimes adding G after the iron loss value indicates high magnetic induction. For example, DQ133 indicates that the iron loss value is 1.33 and the thickness of the cold-rolled oriented silicon steel strip (sheet) is 0.3mm. The new model is 30Q133.

(3) Hot-rolled silicon steel plate Hot-rolled silicon steel plate is indicated by DR. It is divided into low silicon steel (silicon content 2.8%) and high silicon steel (silicon content> 2.8%) according to the amount of silicon content. Representation method: DR + iron loss value (repeated magnetization with 50HZ and sinusoidal change of the maximum magnetic induction intensity of 1.5T per unit weight iron loss value) 100 times + 100 times the thickness value. For example, DR510-50 indicates a hot rolled silicon steel sheet with an iron loss value of 5.1 and a thickness of 0.5mm. The grade of hot-rolled silicon steel sheet for household appliances is expressed by JDR + iron loss value + thickness value, such as JDR540-50.

(1) The cold-rolled non-oriented silicon steel strip has a nominal thickness (value of 100 times expansion) + code A + iron loss guarantee value (value of 100 times the iron loss value when the frequency is 50 Hz and the maximum magnetic flux density is 1.5 T) . For example, 50A470 indicates a cold-rolled non-oriented silicon steel strip with a thickness of 0.5mm and a guaranteed iron loss of 4.7.

(2) The cold-rolled oriented silicon steel strip consists of the nominal thickness (value of 100 times expansion) + code G: indicates ordinary materials, P: indicates high-oriented materials + iron loss guarantee value (the frequency is 50HZ, the maximum magnetic flux density is 1.7T The iron loss value at that time is increased by 100 times). For example, 30G130 indicates a cold-rolled oriented silicon steel strip with a thickness of 0.3mm and a guaranteed iron loss of 1.3.
