摘要
09MnNiDR(以前称为0.5Ni)钢,是近10年研制并使用的低合金低温钢,09MnNiDR与16MnDR钢相比能够在较低的温度下有很高的冲击韧性,在-70℃时仍具有大于27J的冲击功,与3.5Ni、9Ni钢相比,在材料的成本上有明显降低。
09 MnNiDR（previously known as 0.5 Ni） steel is low alloy and low temperature steel in nearly 10 years development and the use,compared with 16 MnDR steel,09 MnNiDR had a high impact toughness under the low temperature,even if In-70 ℃,still had the more than 27J impact energy,compared with 3.5Ni、9Ni steel,the cost of material are clearly reduced.
