超强度钢铁日本科学技术厅正在开始开发一种超强度钢铁，其强度和寿命均为现在钢铁２倍，被称为“新世纪构造材料（ＳＴＸ—２１）”。钢铁的强度、寿命增加２倍能使运输耗能减少、耐震安全性提高，超大桥、发电厂等大型设施的寿命延长，从而节省资源、减少温室气体二氧化... Super-strength steel Japanese Science and Technology Agency is beginning to develop a super-strength steel, its strength and life are two times the current steel, known as the “New Century Structural Materials (STX-21).” Steel strength, life expectancy increased by 2 times to reduce transport energy consumption, increased seismic safety, large bridges, power plants and other large facilities to extend the life expectancy, thereby saving resources and reduce greenhouse gas dioxide ...
