C52-04 JSC270A COLD ROLLED STEEL SHEETS

Name: China Customized C52-04 JSC270A COLD ROLLED STEEL SHEETS Manufacturers Suppliers Factory - GNEE
Brand: GNEE
SKU: 221019546

Cold-rolled: hot-rolled steel coil for raw material, after acid pickling to remove oxide skin for cold rolling, the finished product is hard roll, because of cold work hardening caused by deformation of continuous cold rolling hard roll strength, increase hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts. Hard coil can be used as a raw material, hot dip galvanized factory for hot dip galvanizing unit Settings are annealed wire. Hard coil weight generally in June to 13.5 tons, steel at room temperature, for continuous rolling of hot rolled pickling volumes. Inner diameter is 610 mm.

Classification

Ordinary steel：Mild steel sheet

High tensile strength steel：BH type steel sheet,Commercial type steel sheet,High YR type steel sheet,High r-value type steel sheet,Low YR type steel sheet

This brand is Ordinary steel(Mild steel sheet);Applicable nominal thickness:0.3 to 0.32

The performance specifications

Manufacture with good performance, namely by cold rolling, the thickness can be thinner, higher precision cold-rolled strip steel and steel plate, high straightness, surface finish, surface clean bright, easy to manufacture plating processing, many varieties, wide application, high stamping performance and no limitation at the same time, the characteristics of low yield point, so the manufacture wide range of USES.

Characteristics

(1) the lubrication and cooling technology, reduce the resistance to deformation when rolling and cooling roll;

(2) using high tension rolling, lower resistance to deformation, maintain the stability of the rolling process. Using the average unit tension value is 10% ~ 60% of material yield strength, is generally not more than 50%;

(3) using multi-channel time rolling. Work hardening caused by cold-rolled material, when the total deformation reached 60% ~ 80%, it difficult to continue to deformation. Therefore, in the middle of annealing, in order to continue rolling after material softening. The intermediate annealing can be repeatedly in order to obtain the required thin belt. Rolling is called rolling between two intermediate annealing time. Annealing of cold rolled strip steel in continuous annealing furnace with gas protection or bell type annealing furnace in (see cold-rolled strip annealing). Cold-rolled strip minimum thickness of 0.05 mm, cold rolled foil can be up to 0.001 mm.

The production process

Not be heated in the production process, so there is no hot rolled often appear defect such as pitting and tin oxide, good surface quality, high degree of finish. And the size of the cold rolled products of high precision, the product performance and organization can satisfy some special requirements, such as electromagnetic performance, deep drawing performance, etc.

Scope of application

Main application and manufacture building (building roof panel, roof grille, etc.), animal husbandry, fisheries, food storage, meat and aquatic products frozen processing equipment), automotive (corrosion resistant parts), household appliances (such as civil chimney, kitchen utensils),etc.

The processing technology

Stamping, furnishing articles, kaiping, laser blanking
