Weartech SHS®9500U

Overlay Description

SHS9500U is an iron based steel alloy featuring medium hardness, high toughness and high wear resistance.

Key Performance Characteristics

• 58 - 62 HRC single and double pass weld deposits
• Minimal cracking when applied to plain carbon and alloy steels
• Cost effective: contains no tungsten, molybdenum or nickel
• High resistance to abrasion and galling

Properties

SHS9500U features a unique uniform glass-forming melt chemistry that allows high undercooling to be achieved during welding. This results in considerable refinement of the crystalline microstructure down to a near nanoscale (400 nm length scale) range.

Minimal Cracking

Thermal expansion (CTE) matches engineering grade steels over a wide temperature range. When applied to plain carbon and alloy steels, SHS9500U can be welded without significant preheat (i.e. 600°F) and produce an as-welded bead with minimal cracking.

Wear Resistance

In ASTM G65-04 dry sand/rubber wheel abrasion tests, SHS9500U provides maximum wear resistance of typical mass loss of 0.22 g which results in high abrasion and galling resistance, especially in applications where metal-to-metal friction is likely
