• 对比标准碳等级，可选择低碳含量级别“L”，以避免接缝处的晶体腐蚀（焊接侵蚀）
• 具有较高的抗腐蚀能力
• 低碳可变量最大含量0.03%，消除由于焊接时产生的碳化物的沈淀物。

• The lower carbon “variants”(L) were established as
alternatives to the standard carbon range grade to overcome
the risk of inter-crystalline corrosion (weld decay).
• Higher resistance to corrosive attacks from weather agents.
• Lower-carbon variation with a 0.03% maximum carbon
content that eliminates carbide precipitation due to welding.
