1211 Free-cutting steel bar-Luoyue Precision Metal

Introduction

Carbon steels are steels containing carbon as the chief alloying element. These steels contain aluminium, chromium, copper, nickel, and molybdenum in small quantities. They also contain 0.4% of silicon and 1.2% of manganese. Impurities such as phosphorous and sulfur are also present in these steels.

4. Packaging

  In the steel export activities, we also need to pack the steel to prevent the steel from being scattered in the transportation process. In the hoisting process, it is necessary to lift the steel. So steel is very necessary in the export process. Below is the picture of packaging：



According to the requirements of the state of steel materials, the use of binding, bare, frame, pallet.

Packing standard: according to the following national standard requirements (the parts beyond the requirements will be specified separately)

GB／T191 packaging-pictorial marking for handling of goods

GB／T4857 (all parts) basic test for transport packages

GB／T4879 rustproof packaging

GB／T5048 damp-proof packing
