• Weldable: Can be welded with proper preheat and post-weld procedures

Cons

• Requires heat treatment: Often necessary to achieve optimal properties
• Welding challenges: Requires preheating and controlled cooling to avoid cracking
• Corrosion resistance: Limited; requires coating or plating for corrosive environments
• Not stainless: Will rust without protection
• Dimensional changes: May distort during heat treatment
• Surface decarburization: May lose surface carbon without protective atmosphere

Pros

• Superior strength: Stronger than 44W after heat treatment
• Higher hardness potential: Can achieve higher surface hardness
• Excellent wear resistance: Improved due to higher carbon content
• Deep hardening: Effectively hardens in large sections
• Abrasion resistance: Excellent in high-wear applications
• Good fatigue resistance: Performs well under repeated loads with proper heat treatment
• Retained properties: Maintains hardness at high temperature better than low-carbon steels

Cons

• Reduced toughness: More brittle than 44W, especially at high hardness
• More difficult to weld: Higher carbon content increases risk of cracking
• Requires precise heat treatment: More sensitive to heat treatment parameters
• Reduced ductility: Less tolerant to impact
• Limited corrosion resistance: Not better than 44W; requires protection
• Machining difficulty: Harder to machine, especially when hardened
• Increased risk of distortion: More prone to warping during heat treatment

Pros

• Excellent corrosion resistance: Performs well in most atmospheric and chemical environments
• Superior formability: Easy to form, stretch, and cold stamp
• Excellent weldability: Can be welded by all standard methods without preheating
• Easy to clean: Smooth finish resists bacterial growth
• Non-magnetic: Remains non-magnetic in annealed condition
• High temperature resistance: Maintains strength up to 870°C (1600°F) intermittently
• Excellent cryogenic properties: Maintains toughness at very low temperatures

Cons

• Limited chloride resistance: Susceptible to pitting and crevice corrosion in chloride-rich environments (seawater, salt spray)
• Non-heat-treatable: Cannot be hardened by heat treatment
• Stress corrosion cracking: Can crack under stress in chloride environments
• Work hardening: Can harden significantly during forming, making subsequent operations difficult
• Tendency to gall: Can seize or lock under pressure against itself
• Risk of sensitization: Welding can cause chromium carbide precipitation, reducing corrosion resistance in heat-affected zones

Pros

• Superior corrosion resistance: Excellent resistance to chlorides, acids, and marine environments
• Chemical resistance: Better performance in acidic and chemical environments than 304
• High temperature resistance: Better creep and rupture properties at elevated temperatures
• Excellent weldability: Easily welded without loss of corrosion resistance
• Good formability: Forming characteristics similar to 304
• Non-magnetic: Remains non-magnetic in annealed condition
• Pharmaceutical grade: Preferred for pharmaceutical, medical, and food applications
• Reduced sensitization: Less prone to chromium carbide precipitation than 304

Cons

• Non-heat-treatable: Cannot be hardened by heat treatment
• Work hardening: Work hardening characteristics similar to 304
• Tendency to gall: Can seize or lock under pressure against itself
