OREANDA-NEWS. January 20, 2014. Three National Standards on stainless steel plates and sheets revised by TISCO-- GB/T3280 Cold Rolled Stainless Steel Plate Sheet and Strip, GB/t4237 Hot Rolled Stainless Steel Plate Sheets and Plates, and GB/T4238 Heat-resisting Steel Sheets and Plates--were examined and approved by the examination meeting held in Beijing by Subcommittee 6 on Steel Plates, Sheets and Strips of Technical Committee 183 on Steel of Standardization Administration of China.

The experts attending the meeting firmly believe that the three National Standards have reached the internationally advanced level. The examination and approval of the three National Standards on stainless steel plates and sheets show TISCO strength on R&D and manufacturing of stainless steel and reflect its leading position in China stainless steel industry
 
The equipment and technological level of China stainless steel producers have been improved greatly and a lot of new grades and specifications for stainless steel plates and sheets have been developed since 2007. The original National Standards for stainless steel plates and sheets could not meet the requirements for the development of the stainless steel. In May 2012, TISCO made recommendations to Standardization Administration of China to revise the three National Standards on stainless steel sheets and plates. The project was approved by Standardization Administration of China in Jan.2013. In order to successfully finish the revisions of the standards, TISCO established a standard revision team consisting of outstanding experts from product R&D, standards, inspection and sales departments. After comparing the standards at home and broad, collecting the production data and widely soliciting opinions from the producers and experts in stainless steel industry and users, we made a lot of experiments and verifications, formed the revised draft standards.
   
The revision of the standards received extensive attention from the Chinese relevant authorities, industry associations and all sector of the society. Before the examination and approval of the three standards, a workshop on the three standards was held by Subcommittee 6 on Steel Plates, Sheets and Strips of Technical Committee 183 on Steel of Standardization Administration of China. The participants of the workshop included the professional institutions, such as Stainless Steel Council of China Steel Enterprises Association, the well-known stainless steel experts of China and representatives of stainless steel producers and users. The standard design principles and framework proposed by TISCO were affirmed by the workshop. All the participants agreed that the series 200 stainless steel could not be included into the new standards due to its poor corrosion resistance and difficult to recycle.
 
TISCO has dominated the revision of the standards on stainless steel plates and sheets since 1980s. Based on the latest American standards, with the reference of JIS and European standards and combining with the stainless steel development status of China, the relative systematic and complete new national standards on stainless steel plates and sheets are formed. The newly revised national standards on stainless steel plates and sheets include the widely used and very promising stainless steel grades, expanded the range of specifications and surface finishes and revised the tolerances on chemical analysis, properties and dimensions, which keeps the current pattern of the standards on stainless steel and further standardizes the three types of stainless steel plates and sheets. The newly revised standards meet the requirements of the development and the upgrade of the stainless steel technology and equipment, have stronger economy and applicability and further integrate with the world advanced stainless steel standards.
