ASME SA387 refers to the American Society of Mechanical Engineers (ASME) standard for pressure vessel steel plates made from alloy steel. Specifically, these plates are designed for elevated-temperature service and are suitable for use in boilers and pressure vessels. ASME SA387 includes several grades, each designated by a combination of numbers and letters indicating its composition and properties.

If you are looking for alloy steel sheets according to ASME SA387, you may want to specify the specific grade and class you are interested in, as well as any particular requirements for dimensions and properties. Some common grades under ASME SA387 include:

1. SA387 Grade 11: Chromium-molybdenum alloy steel with good high-temperature strength.

2. SA387 Grade 12: Chromium-molybdenum alloy steel suitable for elevated-temperature applications.

3. SA387 Grade 22: Chromium-molybdenum alloy steel with excellent high-temperature strength.

4. SA387 Grade 91: High-strength chromium-molybdenum alloy steel for elevated-temperature service.

It's important to note that alloy steel sheets under ASME SA387 come in various classes. Class 1 typically denotes plates that are normalized and tempered, while Class 2 plates are usually quenched and tempered.

ASME SA387 or ASTM A387, not "ASTM SA387." Both ASME and ASTM are involved in setting standards, and ASME SA387 and ASTM A387 refer to the same standard for pressure vessel steel plates made from chromium-molybdenum alloy steel.

Here's the correct information:

1. ASME SA387: The American Society of Mechanical Engineers (ASME) sets standards for materials used in pressure vessels, and SA387 is the specific standard for alloy steel plates used for high-temperature service.

2. ASTM A387: The American Society for Testing and Materials (ASTM) also sets standards, and A387 is the equivalent standard to ASME SA387 for the same alloy steel plates.

If you are looking for alloy steel sheets according to ASME SA387 or ASTM A387, you should specify the particular grade and class you are interested in, as well as any specific requirements for dimensions and properties. Common grades include Grade 11, Grade 12, Grade 22, and Grade 91, each designed for different levels of high-temperature strength.

EN 10028-2 is a European standard for pressure vessel steel. It specifies requirements for flat products for pressure equipment made of weldable fine grain steels. The standard is divided into several parts, with Part 2 specifically addressing alloy steels.

If you're looking for sheets made of alloy steel according to EN 10028-2, you would typically be interested in steel grades that fall under this standard. Some common alloy steel grades covered by EN 10028-2 include:

1. 16Mo3: This steel is often used for pressure vessels and boilers at elevated temperatures.

2. 13CrMo4-5: Suitable for use in high-temperature environments, particularly in the oil, gas, and petrochemical industries.

3. 10CrMo9-10: Used for high-temperature and pressure service in the oil, gas, and petrochemical industries.

4. X12CrMo5: This grade is a chrome-molybdenum steel with good high-temperature properties.

5. X10CrMoVNb9-1: Designed for high-temperature applications, especially in the power generation industry.

When referring to "sheets," you are likely interested in flat products like steel plates or sheets. These sheets would be manufactured according to the dimensional and mechanical property requirements specified in EN 10028-2.
