何謂"高強度低合金鋼"(HSLA)急!!20point

高強度低合金鋼的種類有哪些種類

名稱編號

性質有哪些

用途在哪?

麻煩各位高手解答

Update:

謝謝回應

而 A533, Grade B 、A517, Grade F、A543, Class 1

…怎麼分類…而A533、A517、B、F的意思又是?

    高強度低合金鋼是在融化過程中加入了稀有金屬,強度可以達到中強度低合金鋼的兩倍。由於屬非熱處理型,其含碳量 一般均不高於0.15%;由於合金元素含量少,它們多能固溶於肥粒鐵。若以商用觀點而 言,合金量少則成本較低,合於經濟實用原則。

    高強度合金鋼之凹槽韌性、降伏比、焊接性及耐蝕性等優於普通鋼,而加工方法則與 一般碳鋼者無異。

    高強度低合金鋼的ASTM 等級編號有下列數種:

    ASTM A533, Grade B 用途核電廠蒸氣容器等一級設備

    ASTM A517, Grade F 用途橋樑結構物等

    ASTM A543, Class 1, 用途壓力容器,船艦

    ASTM A542, Class 1, 用途化學壓力容器

    ASTM A203, Grade D, 用途低溫設備

    美國材料試驗協會(ASTM) 有關於高強度低合金鋼的詳細列表:

    薄板金

    ASTM A1008 / A1008M - 10 Standard Specification for Steel, Sheet, Cold-Rolled, Carbon, Structural, High-Strength Low-Alloy, High-Strength Low-Alloy with Improved Formability, Solution Hardened, and Bake Hardenable

    薄板金

    ASTM A1011 / A1011M - 10 Standard Specification for Steel, Sheet and Strip, Hot-Rolled, Carbon, Structural, High-Strength Low-Alloy, High-Strength Low-Alloy with Improved Formability, and Ultra-High Strength

    關於板大這個問題,在ASM手冊第一冊有一份詳細的總表(Summary of characteristics and intended uses of HSLA steels described in ASTM specifications),內容包含A242、A572、A588、A606、A607、A618、A633、A656、A690、A709, grade 50 and 50W、A714、A715、A808、A812、A841、A847、A860、A871等計十八種。

    例如:A242

    標題:高強度低合金結構用鋼

    合金元素:鉻、銅、氮、鎳、錫、鈦、釩、鋯

    適當的壓延型式:板、棒以及厚度4英吋以下成型

    特殊性質:大氣腐蝕抵抗性是碳鋼的四倍

    目的用途:焊接、螺栓或鉚接建築構造的結構部分

    A572

    標題:結構品級高強度低合金鈮釩鋼

    ........

    因為限於著作權在此只能做這樣說明,有需要進一步資料來信探討。或者到圖書館或專業書局參閱購買美國ASM手冊。這種書局小弟知道高雄市唯一一家,也是中鋼等鋼鐵從業人員會造訪的專業書店。有需要再提供。
