Cr3-Cr5 forged rolls
Cr3-Cr5 forged rolls are industrial rolling components manufactured by hot forging chromium-alloyed steel ingots to eliminate internal porosity and refine casting structures. These rolls are designed for use in hot and cold rolling mills processing steel, aluminum, and non-ferrous metals. The material composition typically includes 2.8% to 3.5% chromium and 4.5% to 5.5% chromium, with carbon levels between 0.35% and 0.45%, manganese up to 0.8%, and trace amounts of silicon, molybdenum, and vanadium to enhance hardenability and grain control.
Forged rolls of this grade achieve surface hardness in the range of 45 to 58 HRC, with core hardness maintained above 35 HRC to ensure fatigue resistance under cyclic loading. The forging process ensures a dense microstructure with uniform carbide distribution, improving wear resistance compared to cast alternatives. Standard tolerances for diameter and length are typically ±0.5 mm and ±1.0 mm respectively, while surface finish ranges from Ra 1.6 to Ra 3.2 μm. These rolls are commonly supplied with a protective oil coating to prevent corrosion during transit and storage.
These rolls are purchased by rolling mill operators in Asia, Europe, and North America for use in continuous casting lines, plate mills, and strip mills. Buyers typically require certification of material traceability and hardness verification reports. Packaging is usually in steel cradles with wooden end caps, shipped via container or breakbulk. Lead times vary by order size and heat treatment schedule, and Incoterms are commonly FOB Tianjin or CIF destination port.

| Packaging | Steel cradles with wooden end caps (standard for heavy forged rolls) |
Tianjin Hiking Trading Co., Ltd operates from Binhai New Area in Tianjin, China, and functions as a trading intermediary for industrial forged components. The company's trust tier is classified as harbor, indicating verified business registration and basic compliance documentation. There is no public information on manufacturing capacity, workforce size, or years in operation. The listing does not confirm in-house forging facilities, metallurgical testing labs, or direct production of the rolls, only sourcing and export coordination.
The supplier has no recorded response rate or average response time, suggesting limited buyer communication activity. No certifications such as ISO, CE, or material test reports are referenced in the listing. Buyers should treat this entity as a sourcing agent rather than a manufacturer. All product claims must be verified directly with the supplier prior to order placement, as no third-party validation or production history is disclosed.
Cr3-Cr5 forged rolls are high-performance industrial rolls manufactured by forging steel ingots, achieving superior metallurgical quality through elimination of internal porosity and refinement of coarse casting structures. These chromium-alloyed steel rolls are essential components in hot and cold rolling mills across steel, aluminum, and non-ferrous metal industries. Widely traded internationally as heavy industrial forgings, they are sourced from major producers in China, Germany, and Japan, with pricing influenced by chromium alloy content, roll dimensions, and required hardness grades.

Sourcing Cr3-Cr5 forged rolls from Tianjin Hiking Trading Co., Ltd - China Import Guide
Before placing an order, verify the supplier can provide a certified mill test report (MTR) for each heat lot, including chemical composition, hardness profile, and ultrasonic inspection results. Confirm the rolls meet ASTM A621 or ISO 630 standards for forged steel rolls. Do not accept rolls without traceable documentation, as unverified material may fail under operational stress or cause mill downtime.
Confirm Incoterms with the supplier - FOB Tianjin is common, but CIF or DAP may be negotiable. Lead time is typically 30 to 60 days after deposit, depending on forging schedule and heat treatment. Packaging must include steel cradles and wooden end caps to prevent damage during ocean transit. Payment terms often require 30% advance, balance against shipping documents.
Upon arrival, conduct a visual inspection for surface cracks, corrosion, or deformation. Use a Rockwell hardness tester to verify surface hardness at four points around the roll circumference. Check dimensions with calibrated micrometers and compare to the MTR. Retain samples of the oil coating for lab analysis if required. Request a certificate of origin and export declaration for customs clearance.
