| main features | Application examples | |
| 08F | High quality boiling steel with low strength, hardness and excellent plasticity. Deep drawing, good ductility, cold working and weldability Due to the large tendency of component segregation and aging sensitivity, stress relief heat treatment or water toughening treatment can be adopted during cold processing to prevent cold processing fracture |
Easily rolled into sheet, thin strip, cold deformed material, cold drawn steel wire Used as stamping parts, calendering parts, all kinds of non-load-bearing covering parts, carburizing, nitriding, cyaniding parts, and making all kinds of sleeves, profiles, and supports |
| 08 | Extremely soft low carbon steel, low strength and hardness, excellent plasticity and toughness, good cold workability, poor hardenability and hardenability, slightly weaker aging sensitivity than 08F, not suitable for machining, good magnetic conductivity after annealing | Suitable for rolling into sheet, strip, cold deformed material, cold drawing, cold stamping, weldment and surface hardening |
| 1OF lO |
Low strength (slightly higher than 08 steel), good plasticity and toughness, excellent weldability, and no temper brittleness. It is easy to be formed by cold and hot processing, with poor hardenability, and good cutting performance after normalizing or cold processing | Cold rolling, cold stamping, cold heading, cold bending, hot rolling, hot extrusion, hot heading and other processes should be used to form parts that require little stress and high toughness, such as friction plates, deep-drawing vessels, automobile bodies, bullet bodies, etc |
| 15F 15 |
The strength, hardness and plasticity are similar to those of 1OF and 10 steel. In order to improve its cutting performance, it is necessary to normalize or water toughen to properly increase its hardness. Low hardenability, low hardenability, good toughness and weldability | Manufacturing medium and small structural parts, screws, bolts, pull rods, lifting hooks, welding containers, etc. with small stress and simple shape, but high toughness requirements or good welding performance |
| 20 | Strength and hardness are slightly higher than 15F, 15 steel, good plastic weldability, good toughness after hot rolling or normalizing | Make small and medium-sized carburized, carbonitrided and forged parts that are not important, such as lever shaft, transmission fork, gear, heavy mechanical pull rod, shackle, etc |
Packaging |
1. by bundles, each bundle weight under 3 tons, for small outer diameter steel bars, each bundle with 4 - 8 steel strips. 2. after making by bundle, covered with Polyethylene waterproof cloth. 3. make black paints painting on each bar, then make bundles |
| 20 feet container contains dimension | Length under 6000mm |
| 40 feet container contains dimension | Length under 12000mm |
| By bulk vessel | Freight charge is low by bulk cargo, and large heavy sizes can not be loaded into containers can shipping by bulk cargo |
