Stainless Steel Round Bars

Alloy 17-4 is a chromium-copper precipitation hardening stainless steel that is used for applications requiring high strength and a moderate level of corrosion resistance. It is one of the most widely used precipitation hardening grades, as it has high strength hardness up to about 572°F while demonstrating good corrosion resistance in all heat treated conditions. Alloy 17-4 has adequate resistance to atmospheric corrosion or in diluted acid salts where its corrosion resistance is equivalent to Alloy 304 or 430. Alloy 17-4 can be heat treated to a variety of temperatures to develop a wide range of properties. Its mechanical properties can be optimized with heat treatment where very high yield strength up to 180 ksi can be achieved. Alloy 17-4 should not be used at temperatures above 572°F or at very low temperatures.

17-4PH Precipitation Hardening Stainless Steel Alloy (S17400), Type 630, is a chromium-nickel-copper precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance. High strength is maintained to approximately 600°F (316°C).The 17-4 PH stainless steel alloy is martensitic in structure in the annealed condition and is further strengthened by a low temperature treatment which precipitates a copper containing phase in the alloy. In comparison to many alloys in the precipitation hardening family, the S17400 (17-4 PH) alloy requires a simple heat treatment; a one step process conducted at a temperature in the range 900°F (482°C) to 1150°F (621°C) depending on the combination of strength and toughness desired. A wide range of properties can be produced by this one step heat treatment.

Stainless steel 15 – 5 PH, also known as UNS S15500 or XM-12, is a modification of 17-4 PH developed in the 60′s. UNS S15500 stainless steel has a more refined microstructure as a result of the remelting process in which it was developed. This refined structure enhances toughness, especially in the transverse direction of the material. UNS S15500 also has excellent corrosion resistance, good fabricating characteristics and low temperature hardening which makes Stainless Steel 15 – 5 PH® the preferred alloy for many industries.

The composition of UNS S15500 includes small amounts of carbon, manganese, phosphorus, columbium (or niobium), tantalum, silicon and sulphur. 15500 can be forged, welded and formed. Machining may be performed in the solution-annealed state or in the final heat treat condition. Desired mechanical properties such as ductility and strength can be achieved through heating the material at various temperatures.

UNS S15500 is a martensitic precipitation hardening grade. Martensitic stainless steels were designed as a type of alloy which is corrosion resistant and could also be hardened through heat treatment.

Heat treatments are used to strengthen 15-5 alloys. There are eight standard conditions for 15-5 stainless steel after treatment - H 900, H 925, H 1025, H 1075, H 1100, H 1150 and H 1150-M. Heat treating 15-5 PH follows the following steps:

• Conditioning using austenite.
• Air cooling, which turns the austenite into martensitic.
• Precipitation hardening until the desired condition is reached.

Chandan Steel World provides the following 15-5ph products as below:-

317L is a molybdenum containing austenitic stainless steel, with improved corrosion resistance over 304/304L and 316/316L stainless steel. The increased levels of chromium, nickel and molybdenum over 316L stainless steel improve chloride pitting resistance and general corrosion. Through the controlled addition of nitrogen it is common for 317L to meet the mechanical properties of 317 straight grade, while maintaining a low carbon content.

Stainless steel 440C, also known as UNS S44004, principal elements are .95% to 1.2% carbon, 16% to 18% chromium, .75% nickel, with traces of manganese, silicon, copper, molybdenum, phosphorus and sulfur. Grade 440C is a high carbon martensitic stainless with moderate corrosion resistance good strength, and the ability to obtain and hold excellent hardness (Rc 60) and wear resistance. It is considered to be slightly cold workable by common practices and does respond to heat treatment.

15-5 PH Sheet
15-5 precipitation hardened (PH) stainless steel sheet exhibits good transverse strength and fatigue resistance as well as good corrosion resistance. It is a cost-effective material, offering many of the same properties as more expensive high-nickel, non-ferrous alloys. Its high performance in high wear, corrosive environments make it a popular material for many industrial applications, especially for the aerospace, food service, metalworking, chemical and petrochemical industries.
While inherently strong and durable, 15-5 PH stainless steel can be further strengthened with a three-step heat-treatment process. The first step is to condition the metal using austenite. Step two is to allow the metal to cool until the austenite turns to martensite. The final step is to precipitation-harden the stainless steel until it reaches one of eight standard conditions - H 900, H 925, H 1025, H 1075, H 1100, H 1150, H 1150 1150 or H 1150-M. Precipitation hardened stainless steel alloys exhibit improved strength, corrosion resistance, superior durability and performance under heat and stress.
For applications that require performance in high heat conditions, 15-5 PH can be heat treated after it has been precipitation hardened to provide improved resistance to stress corrosion cracking at high temperatures. In order to minimize distortion and stress in the finished product, fabrication is recommended after the metal has been heat treated.
The chemical composition of 15-5 PH is:

Chromium: between 14.0 and 15.50 percent

Nickel: between 3.50 and 5.50 percent

Copper: between 2.50 and 4.50 percent

Columbium plus Tantalum: between 0.15 and 0.45 percent

Manganese: up to 1.00 percent

Silicon: up to 1.00 percent

Carbon: up to 0.07 percent

PH 13-8 Mo* stainless is a martensitic precipitation/age-hardening stainless steel capable of high strength and hardness along with good levels of resistance to both general corrosion and stress-corrosion cracking. In addition, the alloy exhibits good ductility and toughness in large sections in both the longitudinal and transverse directions. The excellent properties of PH 13-8 Mo stainless are obtained through close control of chemical composition and micro structure plus specialized melting which reduces impurities and minimizes segregation. Compared to other ferrous-based materials, this alloy offers a high level of useful mechanical properties under severe environmental conditions.

13-8 Mo stainless has good fabrication characteristics and can be age-hardened by a single low temperature treatment. Cold work prior to aging increases the aging, especially for lower aging temperatures.

13-8 Mo stainless has been used for valve parts, fittings, cold-headed and machined fasteners, shafts, landing gear parts, pins, lock washers, aircraft components, nuclear reactor components and petrochemical applications requiring resistance to stress-corrosion cracking. Generally, this alloy should be considered where high strength, toughness, corrosion resistance, and resistance to stress-corrosion cracking are required in a steel showing minimal directionality in properties.
