Corus had expertise in fancy types of steel that Tata Steel lacked.

康力斯则拥有塔塔钢铁公司所欠缺的各式各样的钢铁技术。

Many new structures are built with a new type of steel joint, an I-joint, which appears to be the most durable type of joint.

许多新式结构都采用了一种新型的钢接合方法，即I形接合，它看来是最耐用的一种接合。

Now, though, a novel type of steel has been developed that resists fractures at much lower temperatures, while retaining its strength and toughness — without the need for expensive additives.

不过现在，一种新型钢材已被研发出来，在更低的温度下也不会断裂，同时保持其强度和韧性——不需要昂贵的添加物。
