GB/T 4171 Q235NH Weather Resistant Steel Sheets

GB/T 4171 Q235NH Weather Resistant Steel Sheets

Q295NH corten steel sheet metal, "Q" represents the letter of yielding pinyin, "235" represents the yield strength of 235MPa, "NH" is the letter of weathering pinyin.

Q295NH weathering-resistant structural steel, delivered in hot rolled, normalized and normalized and tempered condition, has the characteristics of high-quality steel, such as toughness, plastic ductility, molding, welding, abrasion, high temperature and so on.

Q235NH corten sheet Delivery condition: hot rolled, control rolled, normalized, etc.

Q235NH weathering steel sheets Executive Standard: GB/T4171-2008.

Q235NH weathering steel plate Smelting Method:Steel is smelted by converter or electric furnace, and it is sedated steel.

Hot rolled steel is delivered in hot rolled, controlled rolled or normalized condition, Q235NH can be delivered in quenched and tempered condition, cold rolled steel is generally delivered in annealed condition.

Q235NH weathering plate is widely used in: containers, power plants, chimneys, railroad engineering and other outdoor steel, such as large outdoor sculpture steel, weathering steel (i.e., atmospheric corrosion-resistant steel) is between the ordinary steel and stainless steel low alloy steel series of low cost and good quality.

1. Rust-resistant, corrosion-resistant, with 4-8 times higher atmospheric corrosion resistance than general steel;

2. The material can be recycled and utilized, very low carbon and environmental protection;

3. Corrosion-resistant steel life extension, thinning and consumption reduction, labor saving and energy saving;

4. Green, no initial painting; can reduce the use of fireproof paint and fireproof coating, thus reducing pollution, shorten the duration, reduce costs and reduce maintenance, is a kind of "green", sustainable development of the economic class of steel.
