stainless steel sheet meaning

Stainless steel plate refers to the atmosphere, steam and water and other weak medium corrosion steel plate. Acid resistant steel plate refers to acid, alkali, salt and other chemical corrosive medium corrosion of steel plate. Stainless steel plate surface smooth, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion.Different elements have different functions, and there are many JIS grades.

Stainless steel plate is the most common in our life, small to the family with western tableware, indoor piping, water heater, bathtub; Big to auto parts, medical machinery, building materials, chemicals, food industry, textile industry, dairy industry; To achieve aesthetic effect in outdoor environment, it is necessary to use nickel stainless steel. 304 stainless steel is widely used for curtain wall, side wall, roof and other architectural purposes, but in the highly corrosive industrial or Marine atmosphere, it is best to use 316 stainless steel.

• Commonly used steel plate material: 1Cr17Ni7 (SUS301), OCr18Ni9 (ASTM304), 1Cr18Ni9Ti (321), 316,316L, 309S,310S, OCr13 1Cr13.2Cr13.3Cr13 and so on

• Common steel plate specifications for thickness 0.4mm-80mm width 1.m-2.5m and so on

• 201, 202,206, 301,302,304,304L,305,321 all have a density of 7.93.

       309S 310S 316.347 The density of these material specifications is 7.98

       405,410,420, 409, 430 and 434 all have a density of 7.75.

Weight calculation formula of steel plate = Length (unit m) Width (unit m) thickness (unit mm)7.85 Density is different

stainless steel sheet JIS brand introduction

• JIS Japanese Steel (JIS series) ordinary structural Steel is mainly composed of three parts, the first part represents the material, such as: S (Steel) represents the Steel, F(Ferrum) represents the iron; The second part represents different shapes, types and uses, such as P(Plate) for Plate, T(Tube) for Tube, K(Kogu) for tool; The third part represents the characteristic number, which is generally the minimum tensile strength. For example: SS400-- the first S stands for Steel, the second S stands for "Structure", 400 is the lower limit tensile strength of 400MPa, the overall tensile strength of 400MPa ordinary structural Steel.

• SPHC-- the 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. It generally refers to hot rolled Steel Plate and Steel belt.

• SPHD-- Stands for hot rolled steel plate and strip for stamping.

• SPHE-- Stands for hot rolled steel plate and strip for deep drawing.

• SPCC-- stands for cold rolled carbon steel sheet and strip, equivalent to Q195A grade. The third letter, C, stands for Cold. To ensure the tensile test, add T at the end of the brand for SPCCT.

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

• SPCE-- cold rolled carbon steel sheet and strip for deep drawing, equivalent to 08AL(5213) deep drawing steel in China. To ensure non-timeliness, add N to the end of the label for SPCEN. Cold-rolled carbon steel sheet and strip quenching and tempering code: annealing state A, standard quenching and tempering S, 1/8 hard for 8, 1/4 hard for 4, 1/2 hard for 2, hard for 1. Surface processing code: dull finishing for D, bright finishing for B. Spcc-sd stands for cold rolled carbon sheet with standard quenched and matte finish rolling. For example, SPCCT-SB stands for standard quenching and tempering, bright processing, and cold rolled carbon sheet required to ensure mechanical properties.

• JIS mechanical structure with steel grade representation method :S+ carbon content + letter code (C, CK), which carbon content with the median value ×100, letter C: carbon K: carbon with steel. For example, the carbon content of carbon coiling plate S20C is 0.18-0.23%. Three, China and Japan silicon steel plate brand expression method.

Elements contained in stainless steel
