Japanese steel grade standard

Japanese steel product brand representation method JIS (Japanese Industrial Standard) is a Standard by the Japanese Industrial Standard various swim-strokes would (Japanese Industrial Standard Committee abbreviation JISC) made. JIS standard all kinds of iron and steel product standards by the standard code, letter class number, digital class number, serial number, make (or amendment) year composition see table below. Wood material name Card number group into that Cast iron 1. Gray cast iron parts 2. Ductile cast iron parts 3. Blackheart malleable cast iron parts 4. White heart malleable cast iron parts 5. Pearlite malleable cast iron parts FC + minimum tensile strength value, an example: FC15 FCD + minimum tensile strength value, an example: FCD40 FCMB + minimum tensile strength value, an example: FCMB32 FCMW + (P) + minimum tensile strength value, Example: FCMW34 FCMP + minimum tensile strength value, Example: FCMP45 P - pearlite. Tensile strength single bit are N/best callus induction Cast steel 1. Carbon steel casting 2. Structure with high strength carbon steel and low alloy steel castings 3. Alloy steel castings 4. Stainless steel castings 5. Heat resistant steel castings SC + minimum tensile strength value SC + C + serial number SC + symbol of element + digital serial number SCS + digital serial number SCH + digital serial number Tensile strength unit for N/best callus induction C for carbon symbol Some symbol of element using letters code, an example: Cr code for C, Mo, Ni for M for N, Al for A Digital serial number, on behalf of the species Digital serial number, on behalf of the species steel 1. Carbon structural steel S + carbon content + letter code (C, CK) Example: S09C S09CK, Carbon content intermediate value x 100 said. C - carbon, K - carburizing steel 2. Alloy structural steel S + main alloying element symbols + alloy element content mark + carbon content representative value + sign the letter 1. The main alloying element symbolic representation methods: carbon steel symbol for S * * C, Mn steel as the SMn, MnCr steel as the SMnC, Cr steel as the SCr, CrMo steel for SCM, NiCr steel for SNC, NiCrMo for SNCM, AlCrMo steel as the SACM 2. Alloy element content mark for 2,4,6,8 2 in Mn steel containing Mn said > 1.00 ~ < 1.30, in Cr steel that contain Cr > 0.80 ~ < 1.40, in manganese chrome steel that Mn > 1.00 ~ < 1.30, Cr > 0.30 ~ < 0.90, in nickel chrome steel that Ni > 1.0 ~ < 2.0, Cr > 0.25 ~ < 1.25 4 in Mn steel containing Mn said > 1.30 ~ < 1.60, said in chrome steel containing Cr > 0.80 ~ < 1.40, in manganese chrome steel that Mn > 1.30 ~ < 1.60, Cr > 0.30 ~ < 0.90, in nickel chrome steel that Ni > 2.00 ~ < 2.50, Cr > 0.25 ~ < 1.25 And in Mn steel containing Mn said > 1.60, said in chromium steel containing Cr > 1.40 ~ < 2.00, in manganese chrome steel that Mn > 1.60, Cr > 0.30 ~ < 0.90, in nickel chrome steel in Ni > 1.50 ~ < 3.00, Cr > 0.25 ~ < 1.25 8 in chrome steel that Cr > 2.00, in nickel chrome steel that Ni Cr > > 3.0, 0.25 ~ < 1.25, in nickel chrome molybdenum steel that Ni > 3.50, Cr > 0.70 ~ < 1.50, Mo > 0.15 ~ < 0.40 3. Carbon content of representative value: carbon content intermediate value x 100 rounded number, remainder eliminated and 100 times value < 9, the write ten digits 0 4. Additional letter said methods: L said and Pb steel, S says add S steel, U said add Ca steel, H guarantee H, K said carburizing steel 3. Stainless and heat resistant steel S + type symbol + digital serial number, example: SUS301 Steel grade symbol: US said stainless steel, heat-resistant steel UH said. Digital serial number basically refer to American AISI standard 4. Spring steel SUP + serial number, example: SUP3 Serial number said type serial number 5. Containing chromium bearing steel SUJ + serial number, an example: SUJ1 Serial number said type serial number 6. Tool steel S + type symbol + serial number, example: SK1, SK7, SKS2, SKD4 Steel grade symbol: K - carbon tool steel, KC - hollow steel, KD - alloy steel mold, KH - high speed tool steel, KS - alloy special tool steel, KT - forging tool steel 7. Electrical use silicon steel S (or G) + biggest iron loss value (number) + endnotes Cold rolled and hot rolled no orientation with S, cold rolled orientation with G The biggest iron loss value (number) : cold rolled and hot rolled no orientation, said on P10 / when fifty largest iron loss value. Cold rolled orientation said type serial number Tail note: no symbols - cold rolled, F - hot rolled. Suitable for cold rolled and hot rolled no orientation JIS standard steel products brand letter code see table below. code name code name A * * * *, Non-directional electric magnetic steel belt SCP - R Corrugated steel pipe CaSi Calcium silicon iron alloy SCP - RS Corrugated steel pipe D?
