Analysis of "E395" Low-Alloy High-Strength Steel

I. Possible Grade Correlations and Speculations

Current international standards (e.g., EN, ASTM, GB) do not explicitly list an "E395" steel grade. This may be a custom designation in specific industries or enterprises, a typographical error, or a non-standard code for special applications (e.g., marine steel). Below is a detailed analysis:

1. Marine Steel "E-Grade" System

In shipbuilding and offshore engineering, steel is often classified by strength and impact toughness:

 

CCS/IACS Standards: High-strength hull structural steels are divided into Grades A, D, E, and F, corresponding to impact toughness at different temperatures (e.g., Grade E requires impact energy at -40°C). Strength grades are typically denoted by yield strength values, such as E36 (yield strength ≥355 MPa, equivalent to AH36/DH36/EH36 in EN 10225).

Speculation: If "395" in "E395" represents yield strength (MPa), it might refer to a high-strength marine steel with yield strength ≥395 MPa (a lower-grade version of E420). However:

Standard yield strengths in marine steel are 355 MPa (E36), 420 MPa (E46), and 460 MPa (E50); 395 MPa is not a standard value.

Non-standard grades may be custom-developed by enterprises but require classification society certification.

2. Extension of EN 10025 Standards

In the European low-alloy high-strength steel standard (EN 10025), grades like S355 and S420 denote yield strength (MPa). If "E" in "E395" stands for "Engineering Steel" and "395" is the yield strength, it could represent a non-standard grade with yield strength ≥395 MPa. However, this is not listed in EN 10025 (adjacent standard values are S355 and S420).

3. Custom Grades in Other Industries

In mechanical manufacturing and pressure vessel industries, enterprises may develop specific strength grades:

 

A yield strength of 395 MPa falls between S355 (275–420 MPa) and S420 (420–550 MPa), suitable for medium-strength lightweight applications (e.g., crane booms, vehicle structures).

Note: Chemical compositions and mechanical properties of non-standard grades must be provided by manufacturers and are not included in public standards.

II. Comparison with Similar Standard Grades (Yield Strength ≈400 MPa)

For applications requiring properties close to the hypothetical "E395" (yield strength ≈395 MPa), consider the following standard grades:

 

Standard	Grade	Yield Strength (≤16mm)	Key Applications
GB/T 1591	Q390	≥390 MPa	Bridges, vehicles, pressure vessels
	Q420	≥420 MPa	Higher-load structures
EN 10025-3	S420NL	≥420 MPa	Low-temperature structures (-50°C impact)
ASTM A572	Gr. 60	≥415 MPa	General engineering structures
Marine Steel	E42 (CCS)	≥390 MPa	Ship hulls, offshore platforms
