17Mn4 steel plate equivalent

17Mn4 is a steel grade specified under the DIN 17155 standard, which is a German specification for weldable fine-grain steels that are used primarily in pressure vessels and boilers. The 17Mn4 steel plate grade is a manganese-alloyed steel with good weldability and toughness at low temperatures.

Equivalent Grades for 17Mn4 Steel Plate:
While 17Mn4 steel plate is a German standard, similar steel grades can be found under other international standards. Here are some common equivalents:

1. DIN 17155 / EN 10028:
- 17Mn4 steel plate is the exact grade under the DIN 17155 standard. In the more modern EN 10028 standard, a similar grade would be P265GH for pressure vessel applications, although P265GH is generally intended for higher temperatures, while 17Mn4 is used for moderate pressure and temperature applications.

2. ASTM/ASME Equivalent:
- There isn't a direct equivalent in ASTM or ASME standards, but A516 Grade 60 or A537 Class 1 steel may be used for similar applications where moderate pressure and temperature resistance are required.
- A516 Grade 60 is a carbon steel used in the manufacture of pressure vessels and boilers, and shares many of the mechanical properties of 17Mn4.

3. Other International Equivalents:
- JIS G3115 SPV235: This is a Japanese grade for pressure vessel steel with similar mechanical properties to 17Mn4, commonly used for low temperature and medium pressure applications.
- BS 1501-161-430A: A British standard steel plate for pressure vessels that is similar to 17Mn4 steel plate.
