Dimensional tolerances for hot rolled products
Харак теристики ГК Проката | Предельные отклонения |
|---|---|
Rolled thickness (t) 0.40 < t ≤ 1.00 1.00 < t ≤ 2.00 2.00 < t ≤ 4.00 | ± 12% ± 10 % ± 8 % |
Uncut width (W) 30 < W ≤ 800 800 < W ≤ 1300 | Deviations with cut edge less than ±0.6 mm ± 6 mm ± 10 mm |
Length (L) 300 < L ≤ 1500 1500 < L ≤ 6000 | ± 3 mm ± 5 mm |
Flatness | Deviations from flatness per 1 m of rolled length are less than 10 mm |
Crescent shape of rolled products | Less than 10 mm over a length of 3 m |
1) Tolerances meet and exceed the requirements of GOST 19903-2015 for hot-rolled sheets and coils
Dimensional tolerances for cold rolled products
Характеристики ХК Проката | Предельные отклонения |
|---|---|
Rolled thickness (t) 0,40 < t ≤ 0,80 0,80 < t ≤ 2,50 2,50 < t ≤ 4,00 | ± 10 % ± 7 % ± 6 % |
Width (W) | Width deviations less than 2 mm |
Lenght (L) 300 < L ≤ 1500 1500 < L ≤ 6000 | ± 3 mm ± 5 mm |
Flatness | Deviations from flatness per 1 m of rolled length are less than 10 mm |
1) Tolerances meet and exceed the requirements of GOST 19904-90 for cold-rolled sheets and coils
Coatings and Surfaces
Обозначение | Описание | Подходит для |
|---|---|---|
HR (hot rolled) | Hot rolled products | Painting, welding works |
CR (cold rolled) | Cold rolled products | Precision products, stamping, chrome plating |
+Ze(zinc coating) | Galvanized rolled products for corrosion resistance | Increased resistance to rust |
+As (aluminum and silicon coating) | Rolled products with Al-Si coating | High temperature conditions |
1) The surface is lightly oiled to protect against corrosion during transport and short-term storage. Upon request, pipes can be delivered dry; however, in this case, INVEST ZONE will not be responsible for any possible rust.
Шероховатость поверхности, Ra | Значение Ra |
|---|---|
HR, cold rolled | < 0.6 μm |
HR, hot-rolled | < 2.0 μm |
1) Each pack is clearly marked with the production date, steel grade and exact dimensions, ensuring fast loading and traceability.
2) Upon request, sheets can be supplied in other packaging sizes.
