屈服點：拉伸試驗過程中，負(fù)荷不再增加，金屬式樣仍繼續(xù)發(fā)生變形的現(xiàn)象，稱為“屈服”，發(fā)生屈服現(xiàn)象時的應(yīng)力，稱為屈服點或屈服極限。即屈服時的負(fù)荷Ps與式樣原橫截面面積F0之比，σs=Ps/F0，用σs表示，單位符號MPa; </p> <p> <br /> </p> <p> <br /> </p> <p> 屈服強度：對于某些屈服現(xiàn)象不明顯的金屬材料，測定屈服點比較困難，常把產(chǎn)生0.20%長久變形的應(yīng)力定為屈服點，稱為屈服強度或條件屈服極限。用σ0.2表示，單位符號MPa; </p> <p> <br /> </p> <p> 伸長率：金屬材料拉伸時，試樣拉斷后，其標(biāo)距部分所增加的長度與原標(biāo)距長度的百分比。用δ表示，單位符號%; </p> <p> <br /> </p><p> 今年上半年，盡管遭遇**嚴(yán)重沖擊，但中國鋼材市場指標(biāo)好于預(yù)期，尤其是二季度以后，表觀消費呈現(xiàn)V型反彈局面，推動了鋼材及黑色系列商品價格震蕩揚升。預(yù)計中國鋼市下半場可以期待，會比上半年形勢更好。 </p> <p> 需求形勢將會更好 </p> <p> 根據(jù)統(tǒng)計數(shù)據(jù)測算，上半年鋼材國內(nèi)需求超出預(yù)期，今年前5月全國粗鋼表觀消費同比增長3.3%，其中5月份增幅達到6.3%，呈現(xiàn)V型態(tài)勢。由于下半年中國經(jīng)濟增長還會提速，并且固定資產(chǎn)投資成為刺激國內(nèi)需求的重要抓手，鋼材消費力度得到強化，因此“淡季不淡，旺季更旺”，下半場中國鋼材需求量還會更多。由于下半年繼續(xù)提速，所以目前的V型右側(cè)繼續(xù)揚升，終呈現(xiàn)全年“勾型”局面。
