Duplex 2205 Stainless Steel Cylinder Blank

The Duplex 2205 stainless steel cylinder blank from Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. is forged at diameters from 20 mm to 350 mm, with the standard piece at 154 mm diameter × 500 mm length, ready for CNC, lathe, or gun-drilling operations. The wall-thickness math makes the economic case: a pressure vessel in 2205 typically needs only half the wall of a 316L design for the same rating, cutting per-part forging weight by close to half even though the per-kilogram price of 2205 is higher; on finished machined components the saving is usually 15–30 % on raw material cost, with reduced handling, lighter assembly, and lower shipping weight. Procurement teams source a Duplex 2205 stainless steel cylinder blank from Ji lai da because the China manufacturer controls the full forging and QC chain in-house, ships with an EN 10204 3.1 MTC covering chemistry, mechanical properties, and intergranular corrosion testing, and offers third-party inspection by SGS, BV, or TUV on request. Factory-direct FOB, CIF, or DDP pricing removes the trading-company markup. Deep-hole drilling for pre-bored blanks is available as a secondary operation. Send your drawing, final OD × length, bore requirements, and certification add-ons to Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. for a written quote, lead time, and MTC plan returned the same working day.

What It Becomes

High-pressure valve bodies. Subsea connector housings. Desalination pump cylinders. Chemical reactor internals. Heat exchanger tube sheets. The Duplex 2205 stainless steel cylinder blank is starting stock for parts that see both mechanical stress and aggressive chlorides — environments where 316L survives but 2205 thrives at lower wall thickness and lower total weight. Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. forges blanks at diameters 20–350 mm, standard piece 154 mm × 500 mm. Factory-direct China supplier, FOB / CIF / DDP, full MTC per EN 10204.

The 2205 vs 316L Wall-Thickness Math

The case for switching comes down to wall thickness. Take a pressure vessel rated to the same code: 316L needs a calculated wall around 1.0 × the design value, 2205 lands at roughly 0.5 × to 0.55 × because of the higher allowable stress. That cuts per-part forging weight by close to half, even though 2205 costs more per kilogram. On a finished component the saving is usually 15–30 % on raw material cost, plus reduced handling, lighter assembly, and lower shipping weight. China manufacturer pricing on a Duplex 2205 stainless steel cylinder blank from Jiangsu Ji Lai Da Nickel-Based Alloy Co., Ltd. closes most of the gap that used to push buyers back to 316L, and on long runs the total cost of ownership now favors duplex.

Where 2205 Cylinder Blanks End Up by Industry

Where the Duplex 2205 stainless steel cylinder blank actually ships tells the story from a different angle. The same forged 154 × 500 mm blank that becomes a subsea Christmas tree body in West Africa becomes a high-pressure pump cylinder in a Saudi desalination plant, a chemical dosing valve in Gujarat, a tube sheet in a Singapore refinery, or a marine actuator housing in a Korean shipyard. All five segments come off the same forge, the same QC line, and the same MTC per EN 10204, with RFQ turnaround the same working day and delivery on FOB, CIF, or DDP terms.

FAQ

Five questions buyers ask about the Duplex 2205 stainless steel cylinder blank from Ji lai da.

Q1: Why is a 'cylinder blank' different from a round bar?

Same forging process, different intent. A round bar is long relative to its diameter. A cylinder blank is shorter and chunkier — closer to the final component shape. Less material to remove, less machining time, less waste.

Q2: Can 2205 be welded?

Yes, but it requires controlled heat input and matching filler metal (typically 2209). Too much heat shifts the balance toward austenite; too little leaves brittle intermetallic phases. We recommend qualifying your weld procedure per the applicable code.

Q3: When does 2205 beat 316L economically?

When you can reduce wall thickness because of the higher strength. A 2205 pressure vessel uses roughly half the wall of a 316L design for the same rating. Per-part material cost and weight often end up lower despite the higher per-kilogram price.

Q4: Do you supply hollow blanks (bored cylinders)?

Our standard product is solid forged. If you need a pre-bored blank, we can arrange deep-hole drilling — specify bore diameter and tolerance at RFQ.

Q5: What certification do you provide?

EN 10204 3.1 MTC covering chemical composition, mechanical properties (tensile, yield, elongation, hardness), and intergranular corrosion test. Additional tests — impact, ferrite number measurement, PMI — available on request.
