hot brittleness

基本解釋

Causes the steel to produce the hot brittleness, reduces the steel the ductility and the toughness, when forging and rolling crack.
使鋼產生熱脆性，降低鋼的延展性和韌性，在鍛造和軋制時形成裂紋。
The residual deleterious elements in steel lead to products occurring red brittleness surface crack and temper brittleness, and lead to hot strength of heat resistant steel decreasing.
鋼中的殘余有害元素致使鋼材產生紅脆性表面裂紋和具有回火脆性傾向，并使耐熱鋼的熱強性降低。
The residual deleterious elements in steel lead to the products occurring red surface brittleness crack and temper brittleness, and lead to the hot strength of heat resistant steel decreasing.
鋼中的殘余有害元素致使鋼材產生紅脆性表面裂紋和具有回火脆性傾向，并使耐熱鋼的熱強性降低。
