Stainless Steel Bars

Product Details:

The two main properties of precipitation-hardened stainless steels are high corrosion resistance and high strength. Stainless steel grade 17-7 PH is a precipitation hardened stainless steel that possesses high strength and hardness, excellent fatigue properties, good formability, good corrosion resistance, and minimal distortion upon heat treatment. The properties of this alloy are well suited for aerospace applications.

Stainless steel grade 17-7 PH is suitable for use in fresh water and industrial atmospheres, and mild chemical and oxidizing environments. It is recommended that 17-7 PH should not be used in salt water or reducing environments.

Features:

• Sturdiness
• Excellent strength
• Elevated durability

• Nickel: 6.50- 7.75
• Aluminum: 0.75-1.50
• Phosphorus: 0.040 max
• Sulfur: 0.030 max
• Iron: Balance

Physical Properties:

• Density: (Cond. A), 0.282lbs/in³, 7.80 g/cm³
• Electrical Resistivity: (microhm-cm) (all conditions): 68°F (20°C): 80
• Thermal Conductivity: BTU/hr/ft²/ft/°F (W/mK): At 300°F (149°C): 9.5 (16.5)

 

Applications:
Stainless steel grade 17-7 PH is primarily used for applications requiring corrosion resistance, good strength, and mechanical properties up to 427°C (800°F) in operation. It is also commonly used for intricate parts due to its low distortion in heat treatment.


Stainless steel grade 17-7 PH finds uses in the following:

• Variety of springs and washers
• Chemical processing equipment
• Heat exchangers
• Power boilers
• Superheater tubes
• Components used in high-strength/high-temperature conditions

Corrosion Resistance:
17-7 PH stainless steel provides corrosion resistance in conditions TH 1050 and RH 950 is generally superior to that of the standard hardenable chromium types of stainless steels such as Types 410, 420 and 431, but is not quite as good as chromium-nickel Type 304. Corrosion resistance in Condition CH 900 approaches that of Type 304 in most environments.

Formability:
In Condition A, Alloy 17-7 PH can be formed comparably to Type 301. It work hardens rapidly and may require intermediate annealing in deep drawing or in forming intricate parts. Spring-back is similar to that of Type 301. Alloy 17-7 PH is extremely hard and strong in Condition C. Therefore, fabrication techniques for such materials must be used.

Product Details:

Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications it is common to use special "304DDQ" (Deep Drawing Quality) variants. Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.

Product Details:

A limitation with 321 is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable. In this case grade 347 is preferred - the niobium performs the same carbide stabilisation task but can be transferred across a welding arc. Grade 347 is therefore the standard consumable for welding 321. Grade 347 is only occasionally used as parent plate material.

Like other austenitic grades, 321 and 347 have excellent forming and welding characteristics, are readily brake or roll formed and have outstanding welding characteristics. Post-weld annealing is not required. They also have excellent toughness, even down to cryogenic temperatures. Grade 321 does not polish well, so is not recommended for decorative applications.

Product Details:

The 15-5 PH alloy was designed to have greater toughness than 17-4 PH. The 15-5 PH alloy is martensitic in structure in the annealed condition and is further strengthened by a relatively low temperature heat treatment which precipitates a copper containing phase in the alloy. 15-5 PH is also referred to as XM-12 in some specifications.

Stainless steel 15 – 5 PH, also known as XM-12 or UNS S15500, is a modification of 17-4 PH developed in the 1960s. It has a more refined microstructure obtained through the remelting process. This refined structure improves toughness of the material. UNS S15500 also has low temperature hardening, good fabrication properties and excellent corrosion resistance, which makes it suitable for many industries. It can be machined in the solution-annealed state or in final heat treat condition. The strength and ductility of UNS S15500 can be enhanced through heating the material at different temperatures.

UNS S15500 is a martensitic precipitation hardening type stainless steel. Martensitic stainless steels were designed to be corrosion resistant and hardened through heat treatment.
