What are the main grades or material of Electro galvanized steel ?

ANSWER: Electro galvanized steel is a commonly used steel variety in industrial production. There are some standards and grades specifically designed for automotive manufacturing.

For example, under the Japanese steel standard JFS A3021, the grades are: JEC270C, JEC270D, JEC270E, JEC270F, JEC270G, JEC270H, JEC340H, JEC340W, JEC370W, JEC390W, JEC440W, JEC590R, JEC340P, JEC370P, JEC390P, JEC440P (cold rolled base sheet );
JFS A3021: JEH270C, JEH270D, JEH270E, JEH310W, JEH370W, JEH400W, JEH440W, JEH490R, JEH540R, JEH590R (hot rolled base sheet)

Some standard grades have a wider range of uses, which can be used for the production of household electrical components, automotive parts, and so on

For example, under the EN10152 standard, the grades are DC01+ZE, DC03+ZE, DC04+ZE, DC05+ZE, DC06+ZE, DC07+ZE

Grades under JIS G3313 standard: SEHC, SEHD, SEHE, SEFH490, SEFH540, SEFH590, SEFH540Y, SEFH590Y, SE330, SE400, SE490, SE540, SEPH310, SEPH370, SEPH400, SEPH440 (hot-rolled base sheet)

JIS G3313: SECC, SECD, SECE, SECF, SECG, SEFC340, SEFC370, SEFC390, SEFC440, SEFC490, SEFC540, SEFC590, SEFC490Y, SEFC540Y, SEFC590Y, SEFC780Y, SEFC980Y, SEFC340H(cold rolled base sheet)

Among the above Electro galvanized steel grades, JEC270C, JEH270C, DC01+ZE, SCEE, and SEHC are general drawing materials, JEC270D, JEC270E, JEH270D, JEH270E, SEHD, SEHE, SECD, SECE, DC03+ZE, DC04+ZE are deep drawing materials, JEC270G, JEC270F, JEH270F, DC05+ZE, DC06+ZE, DC07+ZE, JECF, and SECG as extra deep drawing materials. All other materials are high-strength structural steel.
