Description
Jiangsu Liangyi is professional manufacturer of 17CrNiMo6,17CrNiMo7,18NCD6,820A16 open die forging parts and seamless rolled steel forged rings from china
Following is the shape of 17CrNiMo6,17CrNiMo7,18NCD6,820A16 forging steel material that we could do is:17CrNiMo6 Forged Steel round bars square bars Flat bars Rectangles Bars Rods,17CrNiMo6 Forged forging steel rings seamless rolled rings,17CrNiMo6 Forged Forging Steel Hubs housing shell Sleeves Bushes Bushing Cases Hollow Bars,17CrNiMo6 forging forged steel shafts,gear,pinion shafts,spindles,gear wheel,17CrNiMo6 Forged Forging Steel Discs Disks Blocks plates,17CrNiMo6 Forged Forging Steel Pipe Tubes Tubings Piping Shells Casings Case barrels Housings.
17CrNiMo6 is Chrome – Nickel – Moly carburising steel, generally supplied annealed to HB 229 max. Carburised and heat treated it develops a hard wear resistant case of about Rc 60-63 and a tough strong core with a typical tensile strength range of 900-1300 MPa, in small to fairly large sections.
17CrNiMo6,17CrNiMo7 forged material Specification, Test results and Documentation are required to prove the following:
Melt analysis following to EN 10084:
Combined Phosphorus(P) and Sulfur(S) content should not exceed 0,040.
Requests for acceptance must be addressed to the purchaser for O2max up to 0,0025.
. Grain size: ASTM 5 and finer (ensured) for 17CrNiMo6,17CrNiMo7 forged gear shafts
. Degree of purity: Determination per melt according to ISO 4967 Method A, or ASTM E45 method B, on basis of an evaluation area of 200 mm2 and the following acceptance values:
Remark: By statistical analysis the assurance of the degree of purity can be agreed.
. Jominy values acc. to EN 10084 (restricted hardenability band). Following values at an austenitising temperature of 860 °C (Determination by calculation permitted):
Brinell hardness max. 217 HB
To calculate the mechanical parameters of 17CrNiMo6,17CrNiMo7,18NCD6,820A16 forged parts, the requirements made of the sample coupon form in EN 10002 and EN 10 045 Part 1 apply. For the heat treatment of the coupon the following requirements must be met:
Hardening: Hardening Temperature 860° C +/- 10° C
Hold Time 2h
Quenched in a fluid medium
Tempering: Tempering Temperature 160° - 210° C
Hold Time 2h
Testing for internal defects (UT) of 17CrNiMo6,17CrNiMo7 forging shafts
The ultrasonic test must be carried out by the supplier . Evaluation is made according to the specifications in the following table:
Residual Magnetic Field and Radioactivity of 17CrNiMo6,17CrNiMo7,18NCD6,820A16 forging rings
Freedom from radioactive contaminations must be ensured by measurement at the still mill. The inspection instruction together with the defined acceptance limits must be submitted.
Furthermore the certificate must confirm that the steel is free of radioactive contaminations and the desired value of max. 8 A/cm residual magnetic field strength is met.
Marking of every finished 17CrNiMo6,17CrNiMo7,18NCD6,820A16 forging gear shafts
The parts must be marked with suitable weather resistant, adhesive labels that can be viewed regardless of the packaging of shipment. The labels have to insure definite material traceability.
All bars have to show:
. Manufacturer
. Melt number.
. Diameter of bar in mm
. Order number and position
. Certificate number
The whole component marking must be protected by the supplier against corrosion and other environmental influences with a suitable preservative medium.
