Introduction

T630 is a 17-4 PH martensitic precipitation hardening stainless steel with a unique combination of high strength and good corrosive resistance. Supplied in either the H1075 (H580) aged condition with a tensile strength of 1000 Mpa minimum (HB 311 min.), or the H1150 (H620) double aged condition with a tensile strength of 930 Mpa minimum (HB 277 min.). It is characterised by high tensile strength and high yield strength obtained by solution annealing, followed by a single or double low temperature (precipitation) age hardening treatment. Coupled with a corosion resistance comparable to 304 austenitic stainless steel in many corrosive environments.630 in the H1075 (H580) aged condition can be re-aged if necessary at a higher temperature simply by heating at the required temperature for the required duration.630 in the H1075 (H580) And H1150 (H620) aged condition, can also be re-aged at a lower temperature by re-solution annealing, followed by age hardening at the required temperature for the required duration.It is used extensively by the Marine, Aerospace, Chemical, Petrochemical, Food Processing, Paper and general metalwork industries. Here it is employed for applications such as: Pump Shafts, Aircraft Fittings, Valve Stems, Hydraulic Fittings, Studs, Bushings, Screws, Fasteners, Couplings, Wear rings, Rollers and Food Handling Equipment etc.. Material Magnetic in all conditions.

Stainless steels are known as high-alloy steels. They contain about 4-30% of chromium. They are further divided into martensitic, austenitic, and ferritic steels. Another group of stainless steels are known as precipitation-hardened steels. They are a combination of austenitic and martensitic steels.

Grade 17-4 stainless steel is the most widely used steel of the precipitation hardening grade steels. It has high toughness, strength, and corrosion resistance..

Features:

  • Excellent durability
  • Fine finish
  • Sturdiness
COMPOSITION

Carbon 0.07 max. Manganese 1.00 max. Phosphorus 0.040 max. Sulfur 0.030 max. Silicon 1.00 max. Chromium 15.00 - 17.50 Nickel 3.00 - 5.00 Copper 3.00 - 5.00 Columbium plus Tantalum 0.15 - 0.45
Grinding and Polishing

440C in the hardened and tempered condition requires care with finish grinding and polishing to avoid overheating as this can lower the hardness and corrosion resistance.

Elevated Temperature Use

Excellent oxidation resistance up to 1100oF (540oC).Exposure to temperature range 600 – 900oF (290 – 480oC) long term may result in reduced toughness but this can sometimes be minimilized by using higher ageing temperatures. As a general guide for short term exposure at elevated temperatures the ageing temperature should be at least 50oF (28oC) above the working temperature.

Welding

May be welded satisfactorily by shielded fusion and resistance welded processes, however oxyacetylene welding is not recommended due to the posibility of carbon pick up Filler metal when required should be similar to the parent metal if strength is important otherwise standard austenitic stainless filler wire 308L may be satisfactory. Pre-heating is not generally required.Welding in the solution annealed condition may be carried out satisfactorily, however welding in the H1150 (H620) condition reduces the effects of high welding stresses. Following welding in the solution annealed condition, parts can be directly age hardened as required, however those in the H1150 (H620) condition should be re-solution annealed and then age hardened as required.
