ASTM A588 Grade B vs ASTM A959 XM-33

Related Material — 59.7% match based on chemical composition and mechanical property overlap.

ASTM A588 Grade B (ASTM A588) and ASTM A959 XM-33 (ASTM A959:2011) are both steel grades. ASTM A588 Grade B is classified under Structural Steel (Corten / Weathering), while ASTM A959 XM-33 is classified under Stainless Steel — a different category, which is worth noting alongside the chemistry match below. ASTM A588 Grade B is typically used for high-strength low-alloy structural steel with atmospheric corrosion resistance (weathering steel); bridges, transmission/communication towers, gusset plates, exposed structural applications, while ASTM A959 XM-33 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1). ASTM A588 Grade B is defined under ASTM International, originating from United States, while ASTM A959 XM-33 is defined under ASTM International, originating from United States.

As per chemical composition, ASTM A588 Grade B vs ASTM A959 XM-33 is a 59.7% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a related material overall at 59.7%.
