C50 (SAE 1050 / AISI 1050 - DIN 1.7035) Steel
The C50 (SAE / AISI 1050) steel produced by Hasçelik is a medium-carbon engineering steel with approximately 0.50% carbon content, known for its high mechanical strength. It is widely used in machinery manufacturing, automotive, and industrial applications due to its reliability. Manufactured according to DIN 1.0540, this grade is ensured through Hasçelik’s modern steelmaking technologies and stringent quality control processes. C50 steel complies with both domestic and international standards and delivers excellent performance in every industrial application thanks to its machinability and heat treatment capability.
C50 steel is a medium-carbon steel that can be hardened by heat treatment. It corresponds to the SAE / AISI 1050 and DIN 1.0540 standards. Thanks to its high tensile strength, wear resistance, and good machinability, it is commonly used in machine parts, shafts, gears, axles, and automotive components. Hasçelik produces C50 steel using modern steelmaking technologies, offering a reliable, performance-focused product that meets both local and international quality standards.
C50
• The “C” indicates carbon steel.
• The number “50” represents a carbon content of approximately 0.50%, placing the steel in the medium-carbon category and allowing hardness through heat treatment.
SAE / AISI 1050
• SAE (Society of Automotive Engineers) and AISI (American Iron and Steel Institute) are American steel standard organizations.
• 1050 denotes a medium-carbon steel with about 0.50% carbon.
DIN 1.0540
• DIN (Deutsches Institut für Normung) is the German standards institute.
• 1.0540 is the designation of this steel in the German standard system.
CK50 / C50E
• CK50 refers to carbon steel (C) with approximately 0.50% carbon. The “K” indicates controlled sulfur and phosphorus levels.
• C50E is a variant with low sulfur (S) and phosphorus (P) content and high purity.
C50 (SAE / AISI 1050) steel is identified with different codes across countries and standards, which is crucial for international trade and technical documentation:
• American Standards (SAE / AISI): 1050
• German Standard (DIN): 1.0540 – C50
• European Standard (EN): C50E / CK50 – EN 10083-2
• Japanese Standard (JIS): S50C
• French Standard (AFNOR): XC48
• British Standard (BS): 080A47
While these codes may look different, they are chemically and mechanically equivalent. Hasçelik ensures C50 steel production fully aligns with international equivalents, making it reliable for export markets.
a) Mechanical Properties
C50 (SAE / AISI 1050) steel offers a balanced combination of strength and machinability. Properties vary depending on the delivery condition (hot-rolled, normalized, annealed, or quenched and tempered). Typical values under standard production and heat treatment:
• Tensile Strength: 600 – 800 MPa (annealed), 800 – 1000 MPa (heat treated)
• Yield Strength: 350 – 550 MPa
• Elongation (A5): 10 – 18%
• Hardness (Brinell – HB): 170 – 220 HB (annealed), 200 – 300 HB (after heat treatment)
Hasçelik optimizes mechanical properties using modern production techniques to suit application requirements.
b) Chemical Composition
C50 (SAE / AISI 1050) steel is a medium-carbon steel. Typical composition according to DIN 1.0540:
• Carbon (C): 0.47 – 0.55%
• Manganese (Mn): 0.50 – 0.80%
• Silicon (Si): 0.15 – 0.35%
• Phosphorus (P): max. 0.040%
• Sulfur (S): max. 0.040%
Element Functions:
• C: Increases hardness and strength
• Mn: Improves strength, toughness, and surface quality
• Si: Supports elasticity and strength
• P and S: Usually unwanted impurities; controlled during Hasçelik production
Thanks to its medium-carbon content, high strength, and hardenability by heat treatment, C50 steel has broad industrial applications:
• Machinery Manufacturing: Shafts, axles, bearing bushes, connection elements
• Automotive Industry: Axles, gears, camshafts, steering components, suspension parts
• Hydraulic & Pneumatic Systems: Piston rods, cylinder rods
• Energy & Power Transmission Systems: Gearboxes, chain wheels, power transmission parts
• General Engineering: Parts under high load, tools, and fixtures
Hasçelik delivers steel in custom dimensions, surface qualities, and heat treatment states, meeting diverse industry requirements.
C50 (SAE / AISI 1050) steel is produced according to standards with full quality control. Price depends on:
• Production method (standard, vacuum ingot casting, etc.)
• Dimensions and tolerances
• Special chemical composition requests
• Order quantity
Hasçelik provides competitive prices while maintaining high-quality standards in domestic and international markets. Current kilogram prices and quotations are available via direct contact with the sales team.
