Global leader in stainless rod and Round Bar fabrication services
Daxun employs a team of specialists and professionals. Our staff thoroughly tests everything before putting it into any form. We are well-known in the industry for our exceptional work. We offer SS 420 Round Bars/Rods constructed from high-quality raw materials.
420 stainless steel contains more carbon than 410 stainless steel. 420 grade steel is a ductile and corrosion-resistant steel with a smooth surface after polishing. After polishing, the surface becomes extremely hard, making it resistant to all types of corrosion. It possesses outstanding shaping and welding properties. It can be deeply drawn without cracking. This makes it ideal for creating sinks, hollow utensils, and pans. It possesses great tensile strength. These bars require less maintenance, making them easier to use. These bars are also highly durable, flexible, and resistant to pitting.
Our network of service centers stock stainless steel bar products for fast, ready supply of bar in common sizes and alloys.We also produce custom-sized stainless steel rods and can arrange inventory schedules for quick turnaround in a timely manner if quantities are below factory minimums.Daxun Alloys stocks stainless steel round bars with diameters ranging from 1/16″ to 26″. Round bars are available in nearly every grade of stainless steel, including 302, 303, 304/L, 309/S, 310/S, 316/L, 317/L, 321, 321/H, 347, 347H, 410, 416, 420, 440C, 17-4PH, Duplex 2205, and Alloy 20. Heat treated stainless steel round bars are offered in 17-4PH, H900 temper (on request), H1025, H1150, Double H1150, and H1150M. Other heat-treated tempers can be manufactured upon request. We stock the following 400 series stainless steels: 410, 430, and 416. We also carry 303, 304, and 316/L precision and bearing quality stainless steel round bars. The majority of our inventory consists of our unique machined bar grades: stainless steel round bars that are melted to consistent standards to increase machinability and lower total cost per component.

Types of SS 420 Stainless Steel Rods (6)
-
Daxun Precision ground rods (bright finish) are passed through a grinding machine to achieve precise dimensions, resulting in a bright surface.
-
Cold drawn round bar (bright) is made by cold drawing equipment to obtain a bright surface, which is more suitable for small size stainless steel bars.
-
Daxun Hot rolled stainless steel round bar (black skin) is produced by hot rolling extrusion machine and annealed, without polished round bar surface.

GENERAL PROPERTIES
Alloy 420 round bar is a hardenable martensitic stainless steel bar that is a derivative of Alloy 410. Similar to Alloy 410, it contains at least 12% chromium, which is sufficient to provide corrosion resistance. Alloy 420 contains more carbon than Alloy 410, intended to increase strength and hardness. It has good ductility after annealing, but can be hardened to a minimum Rockwell hardness of 50 HRC, the highest of the 12% chromium grades. Due to its hardening properties, Alloy 420 is rarely welded, but it is conceivable. Martensitic stainless steels were developed for high hardness, which may compromise other qualities. Corrosion resistance is lower than that of ordinary austenitic grades, and their useful operating range is limited by the loss of ductility at sub-zero temperatures and the loss of strength caused by over-tempering at elevated temperatures. The best corrosion resistance is obtained when the metal is hardened and the surface is ground or polished.
Specifications: UNS S42000.
APPLICATIONS:
420 round bar is widely used in applications where excellent corrosion resistance and hardness are required. It is rarely used at temperatures above 800oF (427oC) due to rapid hardening and loss of corrosion resistance. Applications for 420 alloy include:
- Cuttery
- Knife blades
- Surgical instruments
- Needle valves
- Shear blades
- Scissors
- Hand tools
CORROSION RESISTANCE:
- Less resistant than the austenitic grades and the 17% chromium ferritic alloys
- Good resistance in the hardened condition to the atmosphere, foods, fresh water, and mild acids
- Resistance lowered in the annealed condition
- Best with a smooth surface finish
HEAT RESISTANCE:
- Not recommended for use above the relevant tempering temperature because of reduction in mechanical properties
- Scaling temperature is approximately 1202oF (650oC)
MACHINABILITY
- Tough, stringy chip build-up.
- Similar to machining some of the high carbon tool steel
WELDING
- Not commonly welded due to air hardening characteristics.
- Welding may be performed after preheating to 300-400 F
- Post weld tempering at temperature for 2 hours
HOT WORKING
- Recommended to bring temperatures slowly up to 1400, then on to 2000-2200 F
- Furnace cool slowly to avoid cracking, after furnace working
- Reheating is necessary to keep working temperature above 1600 F.
COLD WORKING
- Can withstand only minor cold work.
- Radical forming operations will result in cracking.
ANNEALING
- Anneal at temperatures between 1550-1650 F (843-900 C)
- Allow for slow furnace cooling.
TEMPERING
- Temper at temperatures of 300-400 F
- Air cool for maximum hardness and corrosion resistance.
HARDENING
- Soak at 1850-1950 F to quench in heated oil.
