aisi 5140 steel | aisi 5140 steel bar | Abrasion resistance aisi 5140 steel round bar
AISI 5140 steel also can be called JIS Scr440 and DIN 1.7035 steel. It is one of the alloy steel as well as the most popular steel grades in the productions of the machine. AISI 5140 steel round bar price is on the medium level and it was easy to processing. After tempering and quenching, the toughness, plasticity and wearing resistance of it will get better. Steel normalizing can make the spheroidizing for the organization of steel get easier. And it will raise the machinability of the semi-finished product with the hardness less than 160HBS. Tempering it at the temperature of 550℃-570℃ which can make it get better mechanical property. And the hardenability of it is higher than S45C steel. You can check 5140 Steel chemical composition and mechanical properties as below.

How is ASTM 5140 steel tested?
AISI 5140 Steel Chemical Composition Testing-Spectrometer
We are sae 5140 Alloy Structural Steel for composition testing using spectrometer.The spectrometer one-time excitation of the sample to analyze its composition method is widely accepted by the public at this stage.Compared with traditional analytical methods, the advantages of spectrometers for the detection of modern steel components are fast, accurate and efficient. This method can directly inject solid samples without chemical digestion, which can reduce the human error caused by the digestion process and the constant volume process; to good quality steel.
We ensure the quality of each piece of steel and strictly control the quality inspection. We have focused on the production of 5140 steel for more than ten years. We are a professional, experienced and powerful steel supplier. Please do not hesitate, we will give you satisfactory service and quality.
Songshun specialized in Special Steel for almost 20 years. We can supply mold steel, high speed steel, alloy steel, free cutting steel and etc.Welcome your contact 24 hours a day!!!
