10# – JIS:S10C/S12C Carbon Steel Pipe Krobo Steel

Product Introduction 

10# steel pipe grade: 10 steel 10# steel pipe chemical composition: carbon C: 0.07~0.14″ silicon Si: 0.17~0.37 manganese Mn: 0.35~0.65 sulfur S: ≤0.04 phosphorus P: ≤0.035 chromium Cr: ≤0.15 nickel Ni : ≤0.25 copper Cu: ≤0.25 Mechanical properties of 10# steel pipe: tensile strength σb (MPa): ≥410 (42) yield strength σs (MPa): ≥205 (25) elongation δ5 (%): ≥25 Reduction of area ψ (%): ≥5, hardness: no heat treatment, ≤156HB, sample size: sample 25mm 10# steel pipe heat treatment specification and metallographic structure: heat treatment specification: normalizing, 910 ℃, air cooling. Metallographic Structure: ferrite + pearlite. 10# steel pipe delivery status: delivery without heat treatment or heat treatment (annealing, normalizing or high temperature tempering). Those who require heat treatment status should be specified in the contract. Those marked are delivered without heat treatment.

 

The content of impurity elements such as sulfur (S) and phosphorus (P) is generally controlled below 0.035%. If it is controlled below 0.030%, it is called high-grade high-quality steel, and “A” should be added after the grade, such as 20A; if P is controlled below 0.025%, and S is controlled below 0.020%, it is called super high-quality steel, and its grade should be followed by ” “E” to show the difference. For other residual alloy elements brought into the steel by raw materials, such as chromium (Cr), nickel (Ni), copper (Cu), etc., the content is generally controlled at Cr≤0.25%, Ni≤0.30%, Cu≤0.25%. Some grades have a manganese (Mn) content of 1.40%, which is called manganese steel.

10# Carbon Steel Chemical Composition:

Element Composition (%)
Carbon (C) 0.07-0.14
Silicon (Si) 0.17-0.37
Manganese (Mn) 0.35-0.65
Phosphorus (P) ≤0.035
Sulfur (S) ≤0.040
Chromium (Cr) ≤0.15
Nickel (Ni) ≤0.25
Copper (Cu) ≤0.25

 

Application:

Manufacture parts that require little stress and high toughness, such as automobile bodies, containers, deep-drawn containers, pipes, gaskets, etc., can be used for cold rolling, cold stamping, cold heading, cold bending, hot rolling and other processes. It can also be used as carburized parts and carbonitrided parts with low core strength.

 

Classification By Size:

The length is generally 6000mm, 1250mm,2200mm,12000mm, and the thickness is distinguished by cold rolling and hot rolling. Cold rolling mainly has thickness 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm. The main thickness of hot rolling is 3.0mm, 4.0mm, 6.0mm, 8.0mm, 10.0mm, and the width is generally 1000mm, 1219mm, 1500mm.Please contact customer service for general specifications.

Hot-rolled carbon steel pipe are produced by continuous hot-rolled carbon steel technology with hot-rolled steel strip or cold-rolled steel strip as the substrate. The hot-rolled carbon steel sheet is supplied as a rectangular flat plate by cross-cutting; the hot-rolled carbon steel sheet is supplied in coil form by coiling, and the hot-rolled carbon steel sheet coil can be divided into hot-rolled carbon steel sheet coil and cold-rolled carbon steel sheet Coils, they are mainly used in construction, home appliances, automobiles, containers, transportation and household business and other fields. Especially steel structure construction, automobile manufacturing, steel silo manufacturing and other industries.

 

Their main features are: strong corrosion resistance, good appearance quality, benefit from deep processing, economical and practical, etc.

Application range:

(1) After annealing, it is processed into ordinary cold rolling;

(2) The galvanizing unit with pre-annealing treatment device processes galvanizing;

(3) Panels that basically do not need to be processed.
