What is 1.4948 material?

1.4948 material is an austenitic heat-resistant stainless steel conforming to European standards, equivalent to ASTM 304H. It possesses excellent high-temperature strength, corrosion resistance, and creep resistance, making it ideal for power plants, petrochemical plants, and furnace components. It is a variant of 304 stainless steel, with its performance at temperatures up to approximately 550°C improved by controlling the carbon content (0.04-0.08% C).

 

What is 1.4948 equivalent to?

The European standard grade (1.4948) is equivalent to several international standard stainless steel grades, such as ASTM (304H) and UNS (S30409). Its corresponding Japanese standard grade is (SUS 304H). Its corresponding Chinese standard grade is (06Cr19Ni10H).

 

1.4898 Chemical Composition

"1.4948" indicates heat-resistant austenitic stainless steel, and "X6CrNi18-10" indicates a chromium content of approximately 18% and a nickel content of approximately 10%. Both standards ensure identical mechanical properties (tensile strength 515 MPa, yield strength 205 MPa) and are interchangeable for use in pressure vessels and high-temperature environments. The chemical composition of EN 1.4948 conforms to EN 10088, and the pressure equipment conforms to EN 10028.

What is the density of 1.4898 stainless steel?

The density for 1.4898 stainless steel (also known as AISI 310S or X10CrNi23-13) is typically around 7.98 g/cm³ (7980 kg/m³), a common value for high-chromium, high-nickel austenitic steels, although densities for stainless steels generally range from 7.7 to 8.0 g/cm³.

 

Is 1.4898 stainless steel magnetic?

1.4898 stainless steel (also known as 310S/4841) is generally non-magnetic in its annealed state because it's an austenitic grade, but it can become weakly magnetic if cold-worked (bent, drawn, formed) due to a structural shift to martensite, though it's less magnetic than ferritic/martensitic steels.

 

What are the differences between 1.4948 and 1.4301 stainless steel?

EN 1.4948 (X6CrNi18-10) and EN 1.4301 (X5CrNi18-10) are very similar austenitic stainless steels, both common AISI 304 types, but 1.4948 has slightly higher carbon and nitrogen (X6CrNi18-10 vs X5CrNi18-10), making it often used for higher strength/temperature needs, while 1.4301 is the standard, versatile 304 grade known for good formability and general corrosion resistance, though 1.4948 offers enhanced mechanicals.
