38CrMoAl is a nitrided Alloy Steel with high wear resistance, high
fatigue strength and high strength.
It is mainly used for nitrided parts with precise dimensions after
heat treatment, or various nitrided parts with low impact load and
high wear resistance. Such as boring bar, grinding machine spindle,
automatic lathe spindle, worm, precision screw, precision gear. And
also such as High-pressure valves, valve stems, gauges, templates,
rollers, replicas, cylinder blocks, compressor piston rods,
governors on steam turbines, rotating sleeves, fixing sleeves,
various wear-resistant parts on rubber and plastic extruders, etc.
We dealed with a 38CrMoAl Alloy Steel project before with a middle
east customer .
Order confirm of 38CrMoAl Alloy Steel round bar
Customer need 26 tons 1.8509 alloy steel, Otai Steel engineer
suggest 38CrMoAl to them .There is rare 1.8509 stock material in
China ,all of Chinese steel mill production 38CrMoAl instead of
1.8509.
Customer try to order 1.8550 /1.8507 /1.8519 instead of 1.8509
alloy steel round bar .and our engineer update the folow chemical
composition as below to customer for reference . and customer
Choose 38CrMoAl finally .

The order delivery condition as follow :
–1.Hot Rolled；;Black Surface
–2.Hardness:160~260HB
–3.Length:4000~6000mm
–4.UT-SEP 1921C/C or Better
–5.Chmical Analyzed 38CrMoAl ( or 1.8509 )
–6.Fix Diameter ( Accept the tolerance -/+1.5mm)
–7.SGS or other third party inspection under buyer‘s arrangement
As we prepared the goods ,and informed customer to arrange third
party inspeaction .
Order inspector of 38CrMoAl Alloy Steel Round bar .
The customer arrange AGS test for the goods . (test the Diameter /
Length / Qty (PC) and weight before loading by container )
And there is feedback of the test is ” Uncceptable “for the goods .
Test feedback as follow :
1.The inspection result was failed due to there was rusty mark on
almost all the products
2.There was no scale provided for unit weight check;
3.The actual material on labels was “38CrMoALA” not conformed to
the client spec “38CrMoAl”
4.For the diameter check, for item 3-75×6000-7500mm, the actual
diameter was 73mm. For item 4-80×6000-7500mm, the actual diameter
was 78mm .For item 5-85×6000-7500mm, the actual diameter was 83mm.
For hardness check, material strength test, stainless steel
material check, chemical composition analysis, there was no
equipment or testing report provided on site.so customer accept our
QC’s material test report .
After our QC feedback for the test process of inspector,the
inspector did not do the steel test before ,and there without some
mistake of the test way .
1.First ,the goods is Hot Rolled,Black Surface ,and there is
reasonable with rusted ,Black sueface means the item is Ex-mill
condition cover with Oxide Layer.
If you want the steel without the any rusted, the surface is Bright
Surface with Polish process.
