Product Overview

Description

pd700

Round steel is divided into hot rolling, forging and cold drawing.The specification of hot rolled round steel is

5.5-250 mm.Among them, the small round steel of 5.5-25 mm is mostly supplied in straight strips and is

commonly used for reinforcing bars, bolts and various mechanical parts.More than 25 mm round steel, mainly

used in the manufacture of mechanical parts, seamless steel tube blank.

By chemical composition

(1) low carbon steel

Also known as mild steel, low carbon steel with a carbon content of 0.10% to 0.30% is readily acceptable for

various processing such as forging, welding and cutting, and is often used to make chains, rivets, bolts, shafts,

etc.

(2) medium carbon steel

Carbon steel with 0.25% ~ 0.60% carbon content.Killed steel, semi - killed steel, rimmed steel and other

products.In addition to carbon may also contain a small amount of manganese (0.70% ~ 1.20%).According to

product quality, it can be divided into ordinary carbon structural steel and high-quality carbon structural

steel.Good thermal and cutting performance, poor welding performance.The strength and hardness are higher

than low carbon steel, while the plasticity and toughness are lower than low carbon steel.Without heat treatment,

hot rolled and cold drawn materials can be used directly, or they can be used after heat treatment.The medium

carbon steel after quenching and tempering has good comprehensive mechanical properties.The maximum

hardness that can be achieved is about HRC55(HB538), b 600 ~ 1100MPa.So in the medium strength level of

various USES, medium carbon steel has been the most widely used, in addition to as a building material, but

also used in a large number of manufacturing of various mechanical parts.

(3) High carbon steel

Often referred to as tool steel, the carbon content ranges from 0.60% to 1.70% and can be hardened and

tempered.Hammers and crowbars are made of 0.75% carbon steel;Cutting tools such as drills, taps and

reamers are made of steel with a carbon content of 0.90% to 1.00%.
