A387 Alloy Steel Grade 11 Sheets & Plates

ASTM A387 Grade 11 Alloy Steel Sheets Plates

Piyush Steel is a well-known supplier of ASTM A387 Grade 11 alloy steel sheets and a reliable manufacturer of SA 387 Gr 11 Class 1 and Class 2 alloy plates. For decades, we have focused on supplying high-quality alloy steel products. We provide the right material for your demanding projects.

One of our core specialties is the ASTM A387 Gr 11 Steel grade. This material is a chrome-molybdenum alloy steel. It is designed to perform exceptionally well under high heat. If your application involves elevated temperatures and high pressures, this is the alloy you need. It is well known for being able to withstand heat and creep. This tough material is very important to industries like oil and gas, power generation and chemical processing. A387 Grade 11 Plates are often used to make heat exchangers, pressure vessels, and boilers.

What Is ASTM A387 Grade 11 Alloy Steel Sheets Plates?

The ASTM A387 Grade 11 alloy steel sheets plates are a specific type of chrome-moly steel. It falls under the ASME/ASTM specification A387/SA387. This specification covers pressure vessel plates made of alloy steel. The alloy is primarily based on iron.Chromium (about 1.0%–1.5%) and molybdenum (about 0.44%–0.65%) are its most important parts. These additional features give the steel its unique qualities.The chromium makes it less likely to rust and corrode. The molybdenum makes the steel stronger and stops it from creeping. Creep is the change in shape of a material that happens when it is under stress at high temperatures. A387 Grade 11 Plates are better for high temperature work than regular carbon steel because they have this unique combination. It maintains its mechanical properties and durability even when the heat is on.

Key Features & Benefits

Choosing Grade 11 Alloy Steel Sheets from Piyush Steel gives your project several distinct advantages.

• High-Temperature Performance: It maintains strength and structural integrity in extremely hot environments.
• Corrosion and Oxidation Resistance: The chromium content helps it fight rust and surface damage, especially at high heat.

Quality Testing Performed

All our products undergo strict testing.Before any ASTM A387 Gr 11 Steel is dispatched we put it through several crucial quality checks. These steps make sure that the plate meets both your order's requirements and international standards. We use a Positive Material Identification (PMI) test to find out exactly what chemicals are in the alloy. This makes sure that the right amount of chromium and molybdenum is in the mix.We also do a hardness test to see how well the material resists surface indentations. The Tensile test is an important step. This test checks how strong the material is and how much it can stretch before it breaks. Lastly, our certified company uses Ultrasonic testing to find any cracks or flaws that are hidden deep inside the plate. This strict testing makes sure that you always get the safest, best product.
