Materials Used In Metal Forging

Being one of the top metal forging companies operating within China today, ChinaSavvy stocks a number of forging materials. Please note that we do work with a vast number of materials and that we are not restricted to working with just the metals listed on this page. Should you find that your desired grade is not on the list, please feel free to contact us directly.

ChinaSavvy works with the following forging materials:

 

Alloy Steel

Typically forged by using hot forging processes, alloy steel is one of the most commonly used forging materials. Stronger, tougher and offering more resistance to wear when compared to carbon steel forgings, alloy steel are commonly alloyed with the following materials to enhance its physical properties:

  • Nickel, chromium, silicon, molybdenum, vanadium boron and manganese.

 

Some of the more popular alloy steels used at ChinaSavvy includes:

Note that we also work with Alloy Steel F11, F22 and F91.

Aluminum

Working with a large number of aluminum grades, ChinaSavvy is capable of producing high quality aluminum forgings to rival some of the best metal forging companies operating within the industry today.

Overall, aluminum alloys have a strong resistance to corrosion, while aluminum open die forging, when compared to casting, offers superior internal integrity, maximum impact strength as weel as an elimination of internal voids.

ChinaSavvy, working with a number of aluminum forging materials, offer the following aluminum die forgings:

Stainless Steel

Enhancing the existing qualities of stainless steel, forging is capable of improving stainless steel’s resistance to corrosion as well as creating a continuous grain flow.

ChinaSavvy works with the following forging materials in this category:

Stainless Steel 300 Series

  • Grade 302: Extremely tough and ductile, Grade 302 is non-magnetic , with cold working processes increasing its hardness.
  • Grade 303: This grade has a good resistance to mildly corrosive atmospheres (though this resistance is less than that of Grade 304).
  • Grade 304: This grade exhibits good mechanical properties as well as a good resistance to corrosion.
  • Grade 304-L: A lower carbon variant of Grade 304, this grade has a high ductility and a better resistance to corrosion than Grade 302.
  • Grade 309: A higher resistance to corrosion and a higher strength than Grade 304.
  • Grade 310: A medium carbon austenitic stainless steel, Grade 310 has a good resistance to oxidation.
  • Grade 316: A molybdenum bearing grade of stainless steel, Grade 316 has a better overall resistance to corrosion when compared to Grade 304.
  • Grade 316-L: The low carbon version of Grade 316, this grade is immune to sensitization and offers high stress, rupture, creep and tensile strength.
  • Grade 317: This grade offers a high strength and a high resistance to corrosion. Grade 317 also does not react to heat treatments, but can be hardened by cold working processes.
  • Grade 321: Similar to Grade 304, Grade 321 has a titanium addition of five times the carbon content.
  • Grade 330:This grade has a high resistance to oxidation and carburization (at 2200°F / 1200°c) as well as a high strength.

Stainless Steel 400 Series

  • Grade 403: A straight chromium stainless steel, Grade 403 offers a reasonable resistance to corrosion as well as a resistance to heat and a scaling temperature of 1300°F (704°C).
  • Grade 405: With a chromium content of 12%, it is not recommended that Grade 405 be forged below 1500°F (816°C). This grade is first soaked at a temperature between 1500°F (817°F) and 1600°F (871°C). This temperature is then increased to a range between 1900°F (1038°C) and 2050°F (1120°C). The forging process will then be followed by air cooling and annealing.
  • Grade 410: A general purpose martensitic stainless steel, Grade 410 contains 11.5% chromium. Always magnetic, this grade has good resistance to corrosion (which can be further improved by processes such as quenching, polishing and tempering) and resistance to heat.
  • Grade 414: A martensitic standard grade, Grade 414 is normally employed as a welding filler metal.
  • Grade 416: A free-machining stainless steel, Grade 416 is highly resistant to fresh water, acids, dry air and alkalis. Do note that this grade is less resistant to corrosion than the non-free machining, austenitic grades.
  • Grade 418: A martensitic type of steel, Grade 418 has a high hardness, strength and toughness combined with a good resistance to corrosion.
  • Grade 422: An appealing alternative to Grade 403, Grade 422 has a better strength at higher temperatures. This grade can resist oxidation and scaling up to a temperature of 1400°F (760°C). Grade 422 also has strength and ductility from room temperature to 1200°F (649°).
  • Grade 431: A martensitic, heat-treatable grade, Grade 431 offers a high toughness, tensile properties, torque strength as well as an excellent resistance to corrosion. This grade is heated to between 2100°F (1150°C) and 2200°F (1205°C) and then forged. Note that it is not recommended to forge this grade below 1650°F (900°C).
  • Grade 440-A: A high carbon martensitic stainless steel, Grade 440-A has a good strength and moderate resistance to corrosion. This grade is first preheated to around 1400°F (760°C) and 1500°F (815°C). the temperature is then slowly raised to about 1900°F (1040°C) and 2200°F (1205°C).Note that it is not recommended to forge this grade below 1700°F (925°C).
  • Grade 440-C: Primarily used as a bearing steel, Grade 440-C has a good strength and moderate resistance to corrosion. Forging temperatures are much the same as seen with Grade 440-A.

Precipitation Hardening Grades

  • 13-8 MO: A good resistance to stress and general corrosion cracking, PH Grade 13-8 MO offers a high transverse toughness. This grade also has a high strength, which is achieved through a low temperature heat treatment.
  • 15-5 PH: A chromium-nickel-copper stainless steel, PH Grade 15-5PH has a good strength, a good transverse toughness, a good ductility as well as a corrosion resistance and hardness capability.
  • 17-4 PH: This martensitic stainless steel has an excellent resistance to corrosion, a high strength and a high hardness.
  • 450: With a yield strength almost three times that of Grade 304, Grade 450 has a high strength and high ductility.
  • 455: An advanced martensitic alloy, Grade 455 offers resistance to corrosion and a yield strength three times that of Grade 304.

ChinaSavvy also works with the following forging materials in this category:

  • Duplex Stainless Steel Grades : 2205, 2507 and F-55.
  • Monel: 400 and K 500.

Titanium

Titanium forged products range to include seamless rolled rings, shafts, disks, hubs, flanges, bars and block, to name but a few examples. Offering a combination of strength and a light weight, titanium is commonly the choice in applications where a high strength, high operating temperature, ligh weight or high resistance to corrosion is required.
