3.JCB 5000/0104
-International Standard is to BSC RQT 701
4.JCB 1050/0001 5000/0202 5000/0500
-Material specification was to BS 970-070M20
I can not get the mechanical properties for 070M20 temporarily. So I list all the data available for your information.
We choose 20Mn for the product samples because it seems better than 20 to be used as 070M20. But 20 is much easier than 20Mn to get.
Together with the product samples, the 20Mn and 20 material samples will be delivered for you confirmation.
Please test the sample pieces and thee final decision depends on the test results.
5.JCB 5000/0001
-Material specification was to AISI 1026/BS.5254.HP5/DIN CK24, etc.
But the Yield strength and Tensile strength are some higher than data from other documents. Would you please check it again?
甲烷制氢I take AISI 1026 for JCB 5000/0001 to compare and some documents show that it is similar to Chinese material named 25Mn or 25, DIN standard Ck 25 and BS EN 070M26.
But both the Chinese materials are n ot easy to get, so we choose another higher and easier to get one named 30 for the product samples, compared with which the DIN Ck30 is listed for your information. Together with the product samples, the 30 sample piece will be delivered for your test conclusion.
