High Quantity Aisi 4140 Alloy Tool Steel Solid Round Bar For Structure - China

alloy steels are designated by aisi four-digit numbers and comprise different kinds of steels, each with a composition which exceeds the limitations of b, c, mn, mo, ni, si, cr, and va set for carbon steels.

aisi 4140 alloy steel is a chromium-, molybdenum-, and manganese-containing low alloy steel.

it has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength.

the following datasheet gives an overview of aisi 4140 alloy steel.

4140 steel is a chromium, molybdenum, manganese low alloy steel plate that is known for its toughness, high fatigue strength, and high torsional strength.

test

how is sae 4140 steel tested? our aisi 4140 steel round bar and steel plate composition detection is carried out by a spectrometer, which is fast, accurate and efficient in detection; hardness is tested by a hardness tester, the hardness tester is based on the leeb hardness measurement principle, which can easily and quickly measure a variety of metal materials.

while displaying the hardness measurement value immediately, it can be freely converted between different hardness scales, and the tolerance limit can be set in advance, and it will automatically alarm when it exceeds the range.

1 - measuring range: (170-960)hld, (17-68.5)hrc, (19-651)hb, (80-976)hv, (30-100)hs, (59-85)hra(13-100 )hrb

2 - measurement direction: support 360° (vertical down, oblique down, horizontal, oblique up, vertical up)

3 - hardness scale: richter (hl), brinell (hb), rockwell b (hrb), rockwell c (hrc), rockwell a (hra), vickers (hv), shore (hs)

4 - display: quarter dot matrix lcd

5 - data storage: maximum 500 groups (impact times 32 to 1)

6 - working voltage: 3v (2 aa size alkaline batteries connected in series)

7 - continuous working time: about 100 hours (when the backlight is not turned on) songshun specialized in special steel for almost 20 years.

we can supply mold steel, high speed steel, alloy steel, free cutting steel and etc.
