Worldwide steel specification question?

[5hant]

Hi there,

If someone just says "ss400" in Europe, I believe they are quite unlikely to mean JIS ss400 (which is Japanese). So, what are they talking about?

What is ss400 in Europe? What kind of steel is it, and what classification is ss400 (is it ASTM, is it European - e.g. EN 10025 or what)?

Thank you guys!!

Most likely carbon steel per JIS. Just because your in Europe doesn't exclude the use of JIS material. There is a world steel market.

Hi guys,

Thanks for this. So there is no standard European ss400 or standard US ss400?

I know that there is an ss400 series, (e.g. which includes ss409, ss410 or whatever) which are stainless steels (I think which is European), but not a specific ss400.

I just want someone who knows the ASTM specs well and the European specs well to say "Relax, there is nothing in the European/American specs which can be identified by ss400 alone, 90% chance that they're talking about JIS ss400".

Does such a person hang out at this forum?



Thanks again,
Shant

Shant;
I have not seen this designation in ASTM/ASME material specifications.

5hant,

There are a number of those type of people who hang out in this forum, me included. As metengr noted, the SS400 designation is not used in the ASTM/ASME standards systems. I have not seen it used in the EN (DIN, BSI, etc.) standards system either. I am ~ 95% sure that this is referring to SS400 according to JIS G 3101.

It is time that engineers will add to the metal/material designation number the spec that uses this designation. If I see a designation number or code without the JIS, ASME, ASTM, SAE, AISI, AMS, MIL, GOST, etc. I always ask the customer what the hell it means.

ss400 can be a shortcut for Stainless Steels 400 as any other undefined creature.

This is simlilar to drawings and blueprints that are missing the ISO, ANSI, DIN, etc. epecification. The same drawing will have different meaning, geometric tolerances, etc. in ISO or ANSI.

Just wanted to add that specifying the ANSI, ASME....is not enough it should include the apec version too. Just this week I ordered a gear under the older AGMA 2000-A88 quality class Q7C from a manufacturer/designer in China but the drawing he produced was per AGMA 2015-2-A06 C7 which is much more accurate and expensive class. Engineers should read and study the specs before putting them on paper.

Here in the USA, I have seen others use 300SS to generally designate the 300 series of stainless steel. Likewise, for 400SS to indicate the 400 series. Neither are proper designations in terms for a specification, but it gets the point across in a far less formal manner.

The 3 and 4 digit alloy names that we use in the US are AISI designations. They quit assigning them about 35 years ago.
Don't be sloppy. Either use a UNS number or a specification along with a grade.
The Europeans agreed to start using UNS numbers about 10 years ago, but they still haven't written them into any standards.

If you write a Standard number down as part of a procurement process you are obliged to own a current copy and have read it. The alloy names and grades along with spec numbers are the basis of the contracts. Ambiguity only helps the dishonest.

Ed, Good you can still recall AISI,it is a legacy but still largely prevalent in trade. In India we have EN(emengency number) series for steels. I think the British have forgotten about it, but we still carry on with the colonial past. It is commonly used while ordering

What is the alternative of steel SS 400 (Japanese standard)? Could you tell if you have a supplier in Europe?

The European equivalent of this grade is S275JR
Information is taken from WinSteel software
We have in our database information on CIS producers as well as European companies included in Russian and Ukrainian holdings
only. To answer your question we need information which kind of products of this grade do you need. Please place the precised question on

what is the equivalent of jis ss400

The AISI equivalents of this grade are 1012 and 1015

What are the composition values of S235JRG2 and what is JIS equivalent? Welding of S235JRG2 and JIS SS400?


S235JRG2 European grade has not exact JIS equivalent. SS400 is the closest grade really. See compositions of the grades below:
S235JRG2: C < 0.2%; Mn < 1.4%; P, S < 0.045%;
N < 0.009%
SS 400: P, S < 0.05%, other elements are not defined

IS SS400 PART OF JIS3101 1995 ONLY OR DOES IT COME UNDER OTHER STANDARDS. IN OTHER WORDS IS THERE SO MANY DIFFERENT VERSIONS OF SS400.

In our database Japanese SS 400 is referenced to JIS G 3101, Korean SS 400 is referenced to KS D 3503 only

Need to know about SS400 Coil Steel and it's property ranges. Can you please help me with this request? Also, if this material is usually Pickled & Oiled. Also, what is a US equivalent to this material

The US equivalents of this grade are AISI 1012 and 1015. All other questions are not free

Thanks you guys,

You're the best, and I'm sorted!

Please be assured that in the UK we frequently still refer to steel by the old EN numbers
