15574－1995規(guī)定，厚度不大于3mm的稱為薄板，厚度大于3mm的稱為厚板。厚板還習(xí)慣性分為中板（4～20mm）、厚板（20～60mm）、特厚板（60mm以上）。中厚板材的品種繁多，使用溫度區(qū)域較廣(-200～600℃)，使用環(huán)境復(fù)雜(耐候性、耐蝕性),使用要求高(堅(jiān)韌性、焊接性)。即使相同用途的鋼板，對(duì)材質(zhì)的要求也不盡相同。按照用途，中厚板產(chǎn)品類別有汽車板、鍋爐板、壓力容器板、低合金度板、耐腐蝕板、碳素結(jié)構(gòu)鋼板、合金結(jié)構(gòu)鋼板、造船及采油平臺(tái)鋼板、機(jī)械建筑用鋼板、模具板、橋梁用鋼板、油氣輸送管線用鋼板等。根據(jù)板帶鋼用途的不同，對(duì)其提出的技術(shù)要求也各不一樣，但基于其相似的外形特點(diǎn)和使用條件，其技術(shù)要求仍有共同的方面，歸納起來就是“尺寸精確板形好、表面光潔性能高”。江陰市港都物資有限公司的圓鋼物美價(jià)優(yōu)，有想法不要錯(cuò)過！鹽城專業(yè)圓鋼價(jià)格</p><p
