On TikTok, you might have noticed the term ‘304’ being referenced or used as a hashtag in some videos. But what does it mean? Here’s everything you need to know.

TikTok is a social media platform used by people of all ages, which means that talking about inappropriate subject matters can lead to your account getting suspended or deleted.

Due to the app’s strict moderating rule, creators and users have come up with unique terms and codewords to discuss more taboo or adult-themed topics.

One of the most popular terms on TikTok is ‘accountant,’ which is used to refer to people in the adult entertainment industry. The slang blew up after “struggling actor” Rocky Paterra explained in a song why he prefers to tell people he’s an accountant rather than having to explain what he actually does.

Now, another codeword known as ‘304’ is making the rounds on the app, and many users aren’t sure what it means. Here’s what you should know next time you see the term on TikTok.

What is 304 on TikTok?

A 304 is a term used to refer to a promiscuous woman or sex worker. If you type the number 304 into an old-school LED calculator and flip it upside down, it should look like the word “h*e,” which some use as a slang word for the profession.

The top Urban Dictionary definition for 304 states that it’s “a way you can call a thot or b*tch a h*e without actually calling her that.”

However, the term on TikTok is primarily used by women themselves and does not seem to carry a negative connotation.

Since the short-form video app has banned certain words or phrases, a TikTok community known as ‘304tok’ has emerged, providing a space for sex workers to discuss their experiences, answer questions and educate people.

If there are any other frequently used terms on TikTok that you don’t know the meaning of, you can check out our guide here to find out all about the app’s most popular terms.

Hi all,

I'm fairly new to this board, this will be my first post.
The question I'd like to ask deals with dual certified 304. I've already google-ed this topic a lot but I cant find a satisfying answer to my question.

Right now, the company I work for (we work in e.g. the (petro-)chemical industry) is making a new pipe spec for 304 material.
We didn't have any for 304 spec before, so I thought of, while making the new 304 spec, to use dual certified 304, since it's good available as such, and has almost the same parallels as 316/316L (for which we already had a spec).

Now, the one thing bothering me is that 304L flanges are limited (per ASME B16.5) to 425 deg C, while 304 flanges go up 1500 per ASME B16.5.
If you have dual certified 304/304L flanges, can you then 'just' use such dual certified flanges up to and above 425 deg C?

The second question (not that important but still interesting); what would you have to do if you want to use 304/304L piping systems beyond 1000F (~538 deg C)?
What values for stresses do you then use, how do you do the calculations?
